This is a new and strange form of data analysis, so I'm starting simple and "looking" at some pretty basic stuff.
The constellation of Orion is rising in the early evenings this time of year, so I thought it appropriate to focus on what can be heard when using some data about the seven brightest stars of Orion: Betelgeuse, Rigel, Bellatrix, Mintaka, Alnilam, Alnitak, and Saiph.
What do the angular distances between Betelgeuse and the other six stars sound like? I calculated these distances and translated them into audio frequencies. The shorter the distance, the lower the frequency. And this is what I got:
Orion Angular Distances
I then took the physical distances (in light years) between us and each of these stars, and did the same thing. Again, the shorter the distance, the lower the frequency:
Orion Physical Distances
Finally, I took the visual magnitudes of these seven stars and translated them into audio frequencies. In this case, the brighter the star (smaller magnitude), the higher the frequency. To get this:

The Future of Data Analysis
Most data analysis today is done visually: we use our eyes to study images or plots. Ironically, many researchers do this while listening to their favorite music not realizing that a potentially very important data analysis tool is being underutilized or not utilized at all.
I first came up with this idea back in the Summer of 2012, documented on my Astronomy and Music blog post titled 'Feel The Noise'.
What I'm suggesting is that we begin LISTENING to our data. Our sense of hearing has a dynamic range of 1 trillion! That's 120 dB! No other human faculty is as sensitive, yet we hardly ever use it for anything other than listening to our environment.
So in this first very primitive and preliminary example, I've taken data from the JPL Horizons website to calculate the distances between the four Galilean moons as they revolve around Jupiter during the month of December 2015. Over the course of that month, I measured the distances every 5184 seconds for a total of 500, equally time-spaced samples.
This is what I call "Distance Audio".
Six distance files are created:
As you listen to this track, keep in mind that the lower tones represent smaller distances and higher tones represent larger distances.
Also, take a look at the following plot, which shows you the distances between the moons (y-axis, in kilometers) as a function of time (x-axis):
And here's a 2D version of the same data, here showing the x, y distances. The plots above are the vector sum of these distances. These are what I've been calling "Orbital Ribbons" and they are quite beautiful by themselves. Combined with the sound they make, it's pretty awesome.
Take a listen! Please note that there is a periodic popping or "helicopter" noise. This is an artifact of creating these audio files which I can hopefully eliminate once I understand the process better. For now, please put up with it!

This is only the tip of the iceberg! Any kind of data can be turned into music!
So then I took a random image of M13 from the Sloan Digital Sky Survey:
and then I blurred it a little...
and then I blurred it a little more.
I then took the pixel values (representing intensity) along a column going right through the brightest part of the cluster (near the left edge) and translated those to audio frequencies for each of the three images. A higher tone represents a brighter pixel. I then mixed those into a single track and this is what I got:
This is called "Visual Audio"
A Slice Through M13
And finally, here are the first five lines of the hydrogen Balmer series, converted from nanometers to Hertz, and mixed into a single five second track. This can be done for any spectrum and I'm anxious to listen to the spectrum of our sun, other stars, galaxies, etc.
This is called "Spectral Audio"
Hydrogen Balmer Series
More to Come!
This is a new form of data analysis that needs to be explored! Yes, it can create some interesting and possibly "pretty" sounds, but there is very useful information in those sounds that contains information about the data that might be overlooked!

Here's a composition of mine I just finished. I've had the video for quite a while but didn't know what to do with it until now. Sorry for the poor image quality. Better cameras require dollars that I don't wish to accumulate too much of.

Jupiter Today | 11 September 2015 | Eastern Elongations
Hello! Today all four Galilean moons are at or near their eastern elongations.
JUPITER TODAY is a daily blog about the dynamic Jupiter system for the purpose of monitoring activity.
We start with the overall view of activity with the Jupiter system, showing the orbits of the four Galilean moons:
This is a view of the Jupiter system looking down on it. Following the blue line to the left is the line of sight to Earth, while following the gray line to the left is the line of sight to the Sun. The orbits of the four Galilean moons are shown. The large dots indicate the position of each moon at 0h, 6h, 12h, 18h, and 24h (0h the next day) UTC for this date. From this point of view, the moons revolve around Jupiter in a counter-clockwise motion. For more information about this graphic, see the post from 30 July 2015.
Orbital Motion
The graph below shows the positions of the four Galilean moons over the next 24 hours as seen from Earth. The curved lines show the path of each moon through time. The dark band in the center is Jupiter. The x-axis is the distance, in arc seconds, from the center of Jupiter:
At 0h UTC, Callisto starts the day in quad 1 moving east. Ganymede spends all day in quad 2 moving west. Europa begins the day in quad 1 heading east. Io starts the day in quad 2 moving west.
By 6h UTC, Io is about to begin its transit of Jupiter.
At 12h UTC, Europa is just past its eastern elongation and is now in quad 2 moving west. Callisto is also at its eastern elongation and is joining Europa and Ganymede in quad 2 headed west.
By 18h UTC, Io is at western elongation and is moving into quad 4 heading east.
By 0h UTC tomorrow, Io is firmly in quad 4 moving east. Europa, Ganymede, and Callisto are all in quad 2 moving west.
Apojoves and Perijoves
At 04:49 UTC, Io goes through an apojove at a distance of 423,499.1 km from Jupiter.
Relative Positions and Motions
At 0h UTC, the position of Jupiter is RA 10h 33m 59.5s, DEC +09d 59m 13.9s. The phase angle is 2.110 degrees, which is 0.138 degrees greater than yesterday. The angle between Jupiter and the Sun is 11.368 degrees, which is 0.754 degrees greater than yesterday. The distance between Jupiter and the Sun is 806,595,126.1 km, which is 35,663.8 km further away than yesterday. Jupiter is moving away from the Sun at a velocity of 1,485.99 km/h, which is 0.6 km/h faster than yesterday. Earth is 953,725,530.6 km from Jupiter, which is 449,006.2 km closer than yesterday. Earth is moving towards Jupiter at a velocity of 18,700.59 km/h, which is 1,293.26 km/h faster than yesterday. We continue to accelerate towards Jupiter. What force are we feeling from F=ma???????
Jupiter-Satellite Events
From 06:44 to 09:02 UTC, the shadow of Io transits Jupiter. From 06:59 to 09:17 UTC, Io transits Jupiter.
Glorious Orbital Ribbons
These are the spacial and temporal connections between the four Galilean moons. This is, once again, looking down upon the Jupiter system.
When is the first image of Jupiter after Superior Conjunction going to be taken? If you have one, send it to me!

Tao Teh Ching 43
Here's the one I "randomly" chose today:
The softest of all things
Overrides the hardest of all things.
Only Nothing can enter into non-space
Hence I know the advantages of Non-Ado.
Few things under heaven are as instructive as the lessons of Silence,
Or as beneficial as the fruits of Non-Ado.

Jupiter Today | 10 September 2015 | All End East
Hello! At the end of today, all four Galilean moons are east of Jupiter. A great sight to see, for sure!
JUPITER TODAY is a daily blog about the dynamic Jupiter system for the purpose of monitoring activity.
We start with the overall view of activity with the Jupiter system, showing the orbits of the four Galilean moons:
This is a view of the Jupiter system looking down on it. Following the blue line to the left is the line of sight to Earth, while following the gray line to the left is the line of sight to the Sun.

From this point of view, the moons revolve around Jupiter in a counter-clockwise motion. For more information about this graphic, see the post from 30 July 2015.
Orbital Motion
The graph below shows the positions of the four Galilean moons over the next 24 hours as seen from Earth. The curved lines show the path of each moon through time. The dark band in the center is Jupiter. The x-axis is the distance, in arc seconds, from the center of Jupiter:
At 0h UTC, Io begins the day at western elongation and will be moving into quad 4 headed east. Europa starts the day in quad 4 moving east pretty near Io from Earth's POV. Ganymede spends most of the day in quad 1 moving east. Callisto is in quad 1 moving east one more day.
At 6h UTC, Io is now firmly in quad 4 headed east.
By 12h UTC, Io and Europa are moving behind Jupiter.
By 18h UTC, Io and Europa are now firmly in quad 1 moving east. Ganymede is at eastern elongation and will be moving into quad 2 headed west.
At 0h UTC tomorrow, Io has gone through eastern elongation and is now in quad 2 headed west. Europa continues in quad 1 moving east for another half-day. Ganymede is now firmly in quad 2 moving west. Callisto spends its last full day in quad 1 moving east.
Apojoves and Perijoves
At 07:42 UTC, Io goes through a perijove (closest it will be to Jupiter this orbit) at a distance of 420,046.8 km. At 08:05 UTC, on the same side of the planet Europa goes through an apojove (furthest it will be to Jupiter this orbit) at a distance of 677,643.9 km. Europa is 1.613 times further away from Jupiter than Io.
Relative Positions and Motions
At 0h UTC, the position of Jupiter is RA 10h 33m 10.6s, DEC +10d 03m 56.4s. The phase angle continues to widen and today it's 1.972 degrees, which is 0.138 degrees greater than yesterday. Jupiter also continues to move away from the Sun at an angular separation of 10.614 degrees, which is 0.753 degrees greater than yesterday. The distance between Jupiter and Earth is 954,174,536.8 km, which is 417,968 km closer than yesterday. Jupiter and Earth are moving toward one another at a velocity of 17,415.33 km/h (similar to low Earth orbiting satellites) ad this is 1.294.1 km/h faster than yesterday. Jupiter is 806,559,462.3 km from the Sun, which is 35,649.4 km further away than yesterday. Jupiter and the Sun are moving apart at a velocity of 1,485.39 km/h, which is 0.26 km/h faster than yesterday.
Jupiter-Satellite Events
From 09:27 to 11:59 UTC, Io moves behind Jupiter. From 12:14 to 15:38 UTC, Europa moves behind Jupiter.

Jupiter Today | 08 September 2015 | Apojoves and Perijoves
Hello! Today, there are two apojoves and two perijoves. An apojove is when a moon of Jupiter is furthest away, and a perijove is when it's closest. In a 24 hour time period, we oftentimes see Io go through both an apojove and a perijove. An interesting observation I've made is that the position of Io's apojove is almost directly on the opposite side of the planet from Europa's apojove, and of course this goes for their perijoves also. This also means that Io's apojove and Europa's perijove are on the same side of the planet. In any case, it's a very very cool resonance and I wonder what effects are being felt by these two moons and how does this resonance effect the other moons and Jupiter itself? Curious.....
JUPITER TODAY is a daily blog about the dynamic Jupiter system for the purpose of monitoring activity.
We start with the overall view of activity with the Jupiter system, showing the orbits of the four Galilean moons:
This is a view of the Jupiter system looking down on it. Following the blue line to the left is the line of sight to Earth, while following the gray line to the left is the line of sight to the Sun. The orbits of the four Galilean moons are shown. The large dots indicate the position of each moon at 0h, 6h, 12h, 18h, and 24h (0h the next day) UTC for this date. From this point of view, the moons revolve around Jupiter in a counter-clockwise motion. For more information about this graphic, see the post from 30 July 2015.
Jupiter has moved out of the field of view of SOHO, so no more SOHO images until next superior conjunction. Booooooooooooo!
Orbital Motion
The graph below shows the positions of the four Galilean moons over the next 24 hours as seen from Earth. The curved lines show the path of each moon through time. The dark band in the center is Jupiter. The x-axis is the distance, in arc seconds, from the center of Jupiter:
At 0h UTC, Io starts the day firmly in quad 3 moving west. Europa is just past eastern elongation and is now in quad 2 moving west. Ganymede spends all day in quad 4 moving east and only at the end of the day does it move behind Jupiter. Callisto spends all day in quad 1 headed east.
By 6h UTC, Io is just past western elongation and is now in quad 4 moving east.
By 12h UTC, Io is now firmly in quad 4 moving east. Europa continues in quad 2 headed west.
At 18h UTC, Io has moved behind Jupiter and is now in quad 1 moving east. Europa is transiting Jupiter and will be moving into quad 3 headed west.
By 0h UTC tomorrow, Io is in quad 1 moving east. Europa is past transit and firmly in quad 3 moving west. Ganymede is moving behind Jupiter. Callisto continues in quad 1 moving east.
Apojoves and Perijoves
At 13:13 UTC, Ganymede goes through an apojove at a distance of 1,071,813.3 km. At 13:25 UTC, Io goes through a perijove at a distance of 420,040.3 km. At 13:42 UTC, Europa goes through a perijove at a distance of 664,522.2 km. At 17:43 UTC, Callisto goes through an apojove at a distance of 1,896,585.1 km.
Relative Positions and Motions
At 0h UTC, the position of Jupiter on Earth's celestial sphere is RA 10h 31m 32.5s, DEC +10d 13m 21.4s. The phase angle is 1.696 degrees, which is 0.138 degrees greater than yesterday. The angular separation between Jupiter and the Sun as seen from Earth is 9.110 degrees, which is 0.751 degrees greater than yesterday. The distance between Jupiter and the Sun is 806,488,169.7 km, which is 35,709.7 km greater than yesterday. This means that Jupiter and the Sun are moving away from one another at a velocity of 1,487.9 km/h. The distance between Jupiter and Earth is 954,979,414.2 km, which is 355,765.9 km closer than yesterday. Jupiter and Earth are moving towards each other at a velocity of 14,823.6 km/h. Wow.
Jupiter-Satellite Events
From 14:59 to 19:29 UTC, Io moves behind Jupiter. From 17:25 to 20:16 UTC, Europa's shadow transits Jupiter. From 17:50 to 20:41 UTC, Europa transits Jupiter. From 22:49 to 03:18 UTC tomorrow, Ganymede moves behind Jupiter.
Glorious Orbital Ribbons
These are the spacial and temporal connections between the four Galilean moons. Notice the I-E-G symmetry. This is, once again, looking down upon the Jupiter system.
When is the first image of Jupiter after Superior Conjunction going to be taken? If you have one, send it to me!

Jupiter Today | 07 September 2015 | Callisto Behind
Hello! I had some internet problems the past couple of days due to a wonderful bolt of lightening that zapped my modem. I had my headphones on at the time of the bolt so I actually heard the frying of the modem. It was great.

At 16:12 UTC, Io goes through an apojove at a distance of 423,490.3 km.
Relative Positions and Motions
At 0h UTC, Jupiter is at an RA of 10h 30m 43.3s and DEC +10d 18m 03.9s. The phase angle is 1.558 degrees, which is 0.139 degrees greater than yesterday.

The distance between Jupiter and Earth is 955,335,180.081 km. These distances are now calculated using the JPL Horizons data instead of my previous source. Not sure why they're different (by a few hundred kilometers) so that's something I'll have to look into a little more to see which one is "correct".
Jupiter-Satellite Events
At 02:35 UTC, Europa reappears from behind Jupiter. From 04:39 to 07:12 UTC, Io moves behind Jupiter.

Jupiter Today | 03 September 2015 | Behind Jupiter
Hello!
JUPITER TODAY is a daily blog about the dynamic Jupiter system for the purpose of monitoring activity.
We start with the overall view of activity with the Jupiter system, showing the orbits of the four Galilean moons:
This is a view of the Jupiter system looking down on it. Following the blue line to the left is the line of sight to Earth, while following the gray line to the left is the line of sight to the Sun. The orbits of the four Galilean moons are shown. The large dots indicate the position of each moon at 0h, 6h, 12h, 18h, and 24h (0h the next day) UTC for this date. From this point of view, the moons revolve around Jupiter in a counter-clockwise motion. For more information about this graphic, see the post from 30 July 2015.
Jupiter has just now passed Superior Conjunction. These images blow me away they are so incredibly beautiful. Here's the current SOHO image showing the steady progress of Jupiter across its field of view:
Orbital Motion
The graph below shows the positions of the four Galilean moons over the next 24 hours as seen from Earth. The curved lines show the path of each moon through time. The dark band in the center is Jupiter. The x-axis is the distance, in arc seconds, from the center of Jupiter:
At 0h UTC, Io begins the day just past western elongation and in quad 4 moving east. Europa starts the day in quad 4 moving east also. Io and Europa will be moving together all day today, including behind Jupiter. Ganymede starts the day in quad 1 moving east. Callisto is passing through western elongation and will be in quad 4 headed east.
At 6h UTC, Io is in quad 4 moving behind Jupiter soon. Callisto is now firmly in quad 4 moving east the rest of the day.
By 12h UTC, Io has moved behind Jupiter and is now in quad 1 moving east. Europa is moving behind Jupiter. Ganymede is near eastern elongation and will be moving into quad 2 headed west.
At 18h UTC, Io is near eastern elongation and will be headed into quad 2 moving west.
By 0h UTC tomorrow, Io is firmly in quad 2 moving west. Europa is in quad 1 headed east. Ganymede is now firmly in quad 2 moving west. Callisto continues in quad 4 headed east.
Apojove and Perijoves
At 06:31 UTC, Io goes through a perijove at a distance of 420,046.9 km. At 06:47 UTC, Europa goes through an apojove at a distance of 677,654.5 km.
Relative Positions and Motions
At 0h UTC, Jupiter is at an RA of 10h 27m 26,1s, DEC +10d 36m 53.1s. The phase angle is 1.005 degrees, which is 0.138 degrees greater than yesterday. The angular separation between Jupiter and the Sun as seen from Earth is 5.376 degrees, which is 0.739 degrees greater than yesterday. The distance between Jupiter and the Sun is 806,308,899 km, which is 35,976 km further away than yesterday. Jupiter is moving away from the Sun at a velocity of 1,499.0 km/h, which is 1.167 km/h slower than yesterday. Jupiter and Earth are 956,447,099 km apart, which is 200,488 km further apart than yesterday. Jupiter and Earth are moving towards one another at a velocity of 8,353.667 km/h, which is 1,287.709 km/h faster than yesterday. Do you feel the acceleration??????
Jupiter-Satellite Events
From 07:33 to 09:58 UTC, Io moves behind Jupiter. From 09:37 to 12:47 UTC, Europa moves behind Jupiter.
Glorious Orbital Ribbons
These are the spacial and temporal connections between the four Galilean moons. This is, once again, looking down upon the Jupiter system.
Jupiter is so near Superior Conjunction that photography and other data collection isn't practical. We'll have to wait about a months after SC to start viewing the Jupiter system again.

At 0h UTC, Io begins the day at its eastern elongation and will be in quad 2 moving west. Europa starts today firmly in quad 3 headed west. Ganymede spends all day in quad 1 moving east. Callisto will be in quad 3 moving west one more day.
At 6h UTC, Io is firmly in quad 2 moving west.
By 12h UTC, Io is transiting Jupiter and moving into quad 3 headed west. Europa is at its western elongation and is headed into quad 4 moving east.
At 18h UTC, Io is firmly in quad 3 headed west. Europa is now firmly in quad 4 moving east.
By 0h UTC tomorrow, Io has just passed its western elongation. Europa is still in quad 4 moving east. Ganymede ends the day moving east in quad 1. Callisto is very near its western elongation.
Apojoves and Perijoves
At 09:18 UTC, Io goes through an apojove at a distance of 423,491.0 km.
Relative Positions and Motions
At 0h UTC, the position of Jupiter is RA 10h 26m 36.6s, DEC +10d 41m 35.1s. The phase angle is 0.867 degrees, which is 0.137 degrees greater than yesterday. The angular separation between Jupiter and the Sun is 4.637 degrees, which is 0.734 degrees greater than yesterday. The distance between Jupiter and the Sun is 806,272,923 km, which is 36,004 km further apart than yesterday. Jupiter is moving away from the Sun at a velocity of 1,500.167 km/h, which is 3.166 km/h slower than yesterday. The distance between Jupiter and Earth is 956,647,587 km, which is 169,583 km less than yesterday. Earth and Jupiter are moving towards one another at a velocity of 7,065.958 km/h, which is 1,288.041 faster than yesterday. We are accelerating towards Jupiter. F = ma????
Jupiter-Satellite Events
From 10:21 to 12:39 UTC, Io's shadow transits Jupiter. From 10:28 to 12:46 UTC, Io transits Jupiter.
Orbital Ribbons
These are the spacial and temporal connections between the four Galilean moons. This is once again looking down upon the Jupiter system.
Jupiter is so near Superior Conjunction that photography and other data collection isn't practical. We'll have to wait about a months after SC to start viewing the Jupiter system again.

JUPITER TODAY is a daily blog about the dynamic Jupiter system for the purpose of monitoring activity.
We start with the overall view of activity with the Jupiter system, showing the orbits of the four Galilean moons:
This is a view of the Jupiter system looking down on it. Following the blue line to the left is the line of sight to Earth, while following the gray line to the left is the line of sight to the Sun. The orbits of the four Galilean moons are shown. The large dots indicate the position of each moon at 0h, 6h, 12h, 18h, and 24h (0h the next day) UTC for this date. From this point of view, the moons revolve around Jupiter in a counter-clockwise motion. For more information about this graphic, see the post from 30 July 2015.
Jupiter has just now passed Superior Conjunction. These images blow me away they are so incredibly beautiful. Here's the current SOHO image showing the steady progress of Jupiter across its field of view:

Jupiter Today | 01 September 2015 | Triple Interaction
Hello! Nice symmetry between Io, Europa, and Ganymede today!
JUPITER TODAY is a daily blog about the dynamic Jupiter system for the purpose of monitoring activity.
We start with the overall view of activity with the Jupiter system, showing the orbits of the four Galilean moons:
This is a view of the Jupiter system looking down on it. Following the blue line to the left is the line of sight to Earth, while following the gray line to the left is the line of sight to the Sun. The orbits of the four Galilean moons are shown. The large dots indicate the position of each moon at 0h, 6h, 12h, 18h, and 24h (0h the next day) UTC for this date. From this point of view, the moons revolve around Jupiter in a counter-clockwise motion. For more information about this graphic, see the post from 30 July 2015.
Jupiter has just now passed Superior Conjunction. These images blow me away they are so incredibly beautiful. Here's the current SOHO image showing the steady progress of Jupiter across its field of view:
The graph below shows the positions of the four Galilean moons over the next 24 hours as seen from Earth. The curved lines show the path of each moon through time. The dark band in the center is Jupiter. The x-axis is the distance, in arc seconds, from the center of Jupiter:
At 0h UTC, Io starts the day near western elongation and will be moving into quad 4 headed east. Europa begins the day in quad 2 moving west. Ganymede spends most of the day in quad 4 moving east. Callisto is in quad 3 headed west all day.
By 6h UTC, Io is now firmly in quad 4 moving east.
By 12h UTC, Io is about to move behind Jupiter and Europa will be transiting Jupiter soon.
At 18h UTC, Io is now firmly in quad 1 moving east. Europa has successfully transited Jupiter and is now in quad 3 headed west. Ganymede will be moving behind Jupiter soon.
By 0h UTC tomorrow, Io is very near eastern elongation and is moving into quad 2 headed west. Europa is now firmly in quad 3 headed west. Ganymede has just reappeared from behind Jupiter and is in quad 1 moving east. Callisto continues in quad 3 moving west.
At 09:49 UTC, Ganymede goes through an apojove at a distance of 1,071,889.2 km. At 12:14 UTC, Io goes through a perijove at a distance of 420,039.6 km. On the other side of the planet, Europa goes through a perijove at 12:26 UTC at a distance of 664,518.9km.
At 0h UTC, the position of Jupiter is RA 10h 25m 47.2s, DEC +10d 46m 16.8s. The phase angle is 0.730 degrees, which is 0.135 degrees greater than yesterday. The angular separation between Jupiter and the Sun as seen from Earth is 3.903 degrees, which is 0.726 degrees greater than yesterday. Jupiter is 806,236,919 km from the Sun, which is 36,080 km greater than yesterday. Jupiter and the Sun are moving away from each other at a velocity of 1,503.333 km/h, which is 1.166 km/h greater than yesterday. Jupiter is 956,817,170 km from Earth, which is 138,670 km closer than yesterday. Jupiter and Earth are moving toward one another at a velocity of 5,777.917 km/h, which is 1,282.209 km/h faster than yesterday.
At 13:05, Io moves behind Jupiter. From 14:51 to 17:42 UTC, the shadow of Europa transits Jupiter. From 15:02 to 17:54 UTC, Europa transits Jupiter. At 15:28 UTC, Io reappears from behind Jupiter. At 18:50 UTC, Ganymede moves behind Jupiter. At 22:51, Ganymede reappears from behind Jupiter.
And now the Glorious Orbital Ribbons:

Tao Te Ching Number 38
Every other day or so, I "randomly" pick one of the verses in the Tao Te Ching. I have the John C H Wu translation. I "feel" where in the book to go and then I read that entry.
Today I read Number 38:
High Virtue is non-virtuous;
Therefore it has Virtue.
Low Virtue never frees itself from virtuousness;
Therefore it has no Virtue.
High Virtue makes no fuss and has no private ends to serve;
Low Virtue not only fusses but has private ends to serve.
High humanity fusses but has no private ends to serve;
High morality not only fusses but has private ends to serve.
High ceremony fusses but finds no response;
Then it tries to enforce itself with rolled-up sleeves.
Failing Tao, man resorts to Virtue.
Failing Virtue, man resorts to humanity.
Failing humanity, man resorts to morality.
Failing morality, man resorts to ceremony.
Now, ceremony is the merest husk of faith and loyalty;
It is the beginning of all confusion and disorder.
As to foreknowledge, it is only the flower of Tao,
And the beginning of folly.
Therefore, the full-grown man sets his heart upon the substance rather than the husk;
Upon the fruit rather than the flower.
Truly, he prefers what is within to what is without.

Jupiter Today | 29 August 2015 | Busy Day
Hello! A pretty busy day at Jupiter from Earth's point of view.
JUPITER TODAY is a daily blog about the dynamic Jupiter system for the purpose of monitoring activity.
We start with the overall view of activity with the Jupiter system, showing the orbits of the four Galilean moons:
This is a view of the Jupiter system looking down on it. Following the blue line to the left is the line of sight to Earth, while following the gray line to the left is the line of sight to the Sun. The orbits of the four Galilean moons are shown. The large dots indicate the position of each moon at 0h, 6h, 12h, 18h, and 24h (0h the next day) UTC for this date. From this point of view, the moons revolve around Jupiter in a counter-clockwise motion. For more information about this graphic, see the post from 30 July 2015.
Jupiter has just now passed Superior Conjunction. These images blow me away they are so incredibly beautiful. Here's the current SOHO image showing the steady progress of Jupiter across its field of view:
Here's an image from the SOHO LASCO C3 camera. Jupiter has reappears into this view, but also appearing yesterday is a new sungrazing comet! Keep an eye on this one over the next few days -- no one knows if it'll make it around the sun or not:
The graph below shows the positions of the four Galilean moons over the next 24 hours as seen from Earth. The curved lines show the path of each moon through time. The dark band in the center is Jupiter. The x-axis is the distance, in arc seconds, from the center of Jupiter:
By 0h UTC, Io is moving behind Jupiter and will be going into quad 1 headed east. Europa, Ganymede, and Callisto are all in quad 2 heading west. All three of these moons will transit Jupiter today. No human will see this event. So does it happen?
At 6h UTC, Io is firmly in quad 1 moving east. Europa is just past transit and is now in quad 3 moving west. Ganymede is transiting Jupiter and will be joining Europa in quad 3. Callisto continues in quad 2 headed west.
By 12h UTC, Io is at eastern elongation and is moving into quad 2 moving west. Europa and Ganymede are now firmly in quad 3 moving west the rest of the day.
At 18h UTC, Io is firmly in quad 2.
By 0h UTC tomorrow, Io has transited Jupiter and is now in quad 3 headed west. Callisto is transiting Jupiter and is moving into quad 3 headed west.

At 0h UTC, the position of Jupiter is RA 10h 23m 18.4s, DEC +11d 00m 20.5s. The phase angle is 0.335 degrees, which is 0.112 degrees greater than yesterday. The angular separation between Jupiter and the Sun is 1.785 degrees, which is 0.594 degrees greater than yesterday. The distance between Jupiter and the Sun is 806,128,540 km, which is 36341 km further apart than yesterday. Jupiter is moving away from the Sun at a velocity of 1,515.208 km/h, which is 5.75 km/h slower than yesterday. The distance between Jupiter and Earth is now getting less and less every day at a distance of 957,140,657 km, which is 46,047 km less than yesterday. Jupiter and Earth are moving towards one another at a velocity of 1,918.625 km/h, which is 1,288.792 km/h faster than yesterday. We are now accelerating towards Jupiter.
At 00:08 UTC, Io moves behind Jupiter. From 01:34 to 04:25, Europa's shadow transit Jupiter. From 01:38 to 04:30 UTC, Europa transits Jupiter. At 02:28, Io reappears from behind Jupiter. From 04:49 to 08:24 UTC, the shadow of Ganymede transits Jupiter. From 04:58 to 08:34 UTC, Ganymede transits Jupiter. From 21:24 to 23:42 UTC, the shadow of Io transits Jupiter. From 21:25 to 01:44 UTC tomorrow, the shadow of Callisto transits Jupiter. From 21:27 to 23:45, Io transits Jupiter. From 21:48 to 02:18 UTC tomorrow, Callisto transits Jupiter.
The Glorious Orbital Ribbons:
Jupiter is so near Superior Conjunction that photography and other data collection isn't practical. We'll have to wait about a months after SC to start viewing the Jupiter system again.

JUPITER TODAY is a daily blog about the dynamic Jupiter system for the purpose of monitoring activity.
We start with the overall view of activity with the Jupiter system, showing the orbits of the four Galilean moons:
This is a view of the Jupiter system looking down on it. Following the blue line to the left is the line of sight to Earth, while following the gray line to the left is the line of sight to the Sun. The orbits of the four Galilean moons are shown. The large dots indicate the position of each moon at 0h, 6h, 12h, 18h, and 24h (0h the next day) UTC for this date. From this point of view, the moons revolve around Jupiter in a counter-clockwise motion. For more information about this graphic, see the post from 30 July 2015.
Jupiter has just now passed Superior Conjunction. These images blow me away they are so incredibly beautiful. Here's the current SOHO image showing the steady progress of Jupiter across its field of view:
Here's an image from the SOHO LASCO C3 camera. Jupiter has reappears into this view, but also appearing yesterday is a new sungrazing comet! Keep an eye on this one over the next few days -- no one knows if it'll make it around the sun or not:
The graph below shows the positions of the four Galilean moons over the next 24 hours as seen from Earth. The curved lines show the path of each moon through time. The dark band in the center is Jupiter. The x-axis is the distance, in arc seconds, from the center of Jupiter:
At 6h UTC, Io is firmly in quad 1 moving east. Europa is just past transit and is now in quad 3 moving west. Ganymede is transiting Jupiter and will be joining Europa in quad 3. Callisto continues in quad 2 headed west.
By 12h UTC, Io is at eastern elongation and is moving into quad 2 moving west. Europa and Ganymede are now firmly in quad 3 moving west the rest of the day.
At 18h UTC, Io is firmly in quad 2.
By 0h UTC tomorrow, Io has transited Jupiter and is now in quad 3 headed west. Callisto is transiting Jupiter and is moving into quad 3 headed west.
At 20:41 UTC, Io goes through an apojove at a distance of 423,498.2 km.
At 0h UTC, the position of Jupiter is RA 10h 23m 18.4s, DEC +11d 00m 20.5s. The phase angle is 0.335 degrees, which is 0.112 degrees greater than yesterday. The angular separation between Jupiter and the Sun is 1.785 degrees, which is 0.594 degrees greater than yesterday. The distance between Jupiter and the Sun is 806,128,540 km, which is 36341 km further apart than yesterday. Jupiter is moving away from the Sun at a velocity of 1,515.208 km/h, which is 5.75 km/h slower than yesterday. The distance between Jupiter and Earth is now getting less and less every day at a distance of 957,140,657 km, which is 46,047 km less than yesterday. Jupiter and Earth are moving towards one another at a velocity of 1,918.625 km/h, which is 1,288.792 km/h faster than yesterday. We are now accelerating towards Jupiter.
At 00:08 UTC, Io moves behind Jupiter. From 01:34 to 04:25, Europa's shadow transit Jupiter. From 01:38 to 04:30 UTC, Europa transits Jupiter. At 02:28, Io reappears from behind Jupiter.

Jupiter has just now passed Superior Conjunction. These images blow me away they are so incredibly beautiful. Here's the current SOHO image showing the steady progress of Jupiter across its field of view:
Here is a view of the SC itself also as seen from the SOHO LASCO C2 camera:
The graph below shows the positions of the four Galilean moons over the next 24 hours as seen from Earth. The curved lines show the path of each moon through time. The dark band in the center is Jupiter. The x-axis is the distance, in arc seconds, from the center of Jupiter:
At 0h UTC, Io starts the day in quad 2 moving west. Europa starts the day in quad 1 heading east. Ganymede and Callisto spend all day in quad 2 heading west.
By 6h UTC, Io has transited Jupiter and is now in quad 3 moving west. Europa is at its eastern elongation and is now in quad 2 moving west.
At 12h UTC, Io is coming up on its western elongation and will be moving into quad 4 heading east. Europa is now firmly in quad 2 with Ganymede and Callisto heading west the rest of the day.
By 18h UTC, Io is past western elongation and is now firmly in quad 4 moving east.
At 0h UTC tomorrow, Io is moving behind Jupiter. Europa is about to transit Jupiter. Ganymede and Callisto continue in quad 2 moving west a little while longer.
At 02:21 UTC, Io goes through an apojove at a distance of 423,498.2 km. At 22:09 UTC, Ganymede goes through its perijove at at distance of 1,068,977.8 km. At 23:38 UTC, Io goes through its perijove at a distance of 420,030.1 km. At 23:47 UTC, Europa goes through its perijove at a distance of 664,504.4 km.
At 0h UTC, the position of Jupiter on Earth's celestial sphere is RA 10h 22m 28.8s, DEC +11d 05m 01.1s. The phase angle is 0.223 degrees, which is 0.059 degrees greater than yesterday. The angle between Jupiter and the Sun is now increasing and is at 1.191 degrees, which is 0.319 degrees greater than yesterday. The distance between Jupiter and the Sun is 806,092,199 km, which is 36,479 km greater than yesterday. Jupiter is moving away from the sun at a velocity of 1,519.958 km/h, which is 1.458 km/h faster than yesterday. The distance between Jupiter and Earth is 957,186,704 km, which is 15,116 less than yesterday. Jupiter and Earth are now moving toward one another at a velocity of 629.833 km/h, which is 1,282.458 km/h "slower" than yesterday.
From 02:56 to 05:14, the shadow of Io transits Jupiter. From 02:57 to 05:15, Io itself transits Jupiter.
Now the Orbital Ribbons:
Jupiter is so near Superior Conjunction that photography and other data collection isn't practical. We'll have to wait about a months after SC to start viewing the Jupiter system again.

By 6h UTC, Io and Europa are about to move behind Jupiter.
At 12h UTC, Io and Europa are now both in quad 1 heading east. Ganymede is at its eastern elongation and is now moving into quad 2 headed west.
At 18h UTC, Io and Europa are now firmly in quad 1 moving east. Ganymede is now firmly in quad 2 moving west.
By 0h UTC tomorrow, all four moons are east of Jupiter as seen from Earth.
The position of Jupiter on Earth's celestial sphere at 0h UTC is RA 10h 21m 39.1s, DEC +11d 09m 41.4s. The phase angle is 0.164 degrees, which is 0.044 degrees less than yesterday.

Jupiter is moving away from the Sun at a velocity of 1,518.5 km/h, which is 1.667 km/h slower than yesterday. The distance between Jupiter and Earth is 957,201,820 km, which is 15663 km greater than yesterday. Jupiter and Earth are hardly moving at all relative to one another radially with a velocity of 652.625 km/h, which is 1,286.875 km/h slower than yesterday.
At 05:19 UTC, Io goes through a perijove at a distance of 420,044.7km. At 05:31 UTC, Europa goes through an apojove at a distance of 677,653.5 km.
At 05:40, Io moves into Jupiter's shadow. At 07:00 UTC, Europa moves into Jupiter's shadow. At 07:58 UTC, Io reappears from behind Jupiter. At 09:56, Europa reappears from behind Jupiter.
Now the Orbital Ribbons:
Jupiter is so near Superior Conjunction (taking place at 22:00 UTC on 26 August 2015) that photography and other data collection isn't practical. We'll have to wait about a months after SC to start viewing the Jupiter system again.
