This is Jupiter today for the 17th of January 2015. Jupiter today is a daily podcast focusing attention on the Jupiter system for the purpose of monitoring activity. At 0 hours UTC, the position of Jupiter on the celestial sphere is a right ascension of 9 hours, 30 minutes, 57.7 seconds, and a declination of positive 15 degrees, 39 minutes, 58 seconds. The angular separation from the Sun, as seen from Earth, is 156.264 degrees, and that's 1.129 degrees greater than what it was yesterday. The phase angle, and that's the angle between the Earth and the Sun, is seen from Jupiter. It is 4.262 degrees, getting ever smaller, and that's 0.191 degrees less than what it was yesterday. The distance continues to get shorter too, as we approach opposition on February 6th. The distance today is 659,785,566 kilometers, and that's 953,944 kilometers closer than what it was yesterday. It gives a relative velocity of 39,747.67 kilometers per hour. The two planets coming towards one another, and that velocity is slowing down by still ever increasing rate, and today that velocity slowed down by 1,773.91 kilometers per hour. The central meridian adds 0 hours UTC, CM 165.26 degrees, CM 2, 238.66 degrees, CM 3, 141.67 degrees. It's 0 hours, EO, begins today in Quadrant 2 heading west. Europa is also in Quadrant 2 heading west, and from Earth's point of view you can see they're fairly close to one another, this line is side. The enemy starts today in Quadrant 1 heading east, but it's pretty near at the eastern knee-longation, and Colistoe spends all day in Quadrant 1 slowly heading east. By 6 hours UTC, EO has now transited Jupiter, and Europa is in the process of still transiting. Ganymede is now very near its eastern knee-longation. By 12 hours UTC, EO is in Quadrant 3 heading west, near its western knee-longation. Europa is still in Quadrant 2 heading west, or Quadrant 3 heading west. By 1800 hours, EO is in Quadrant 4 heading east, and by 0 hours UTC, EO is still in Quadrant 4 heading east, near going behind Jupiter from our line of sight. There were nine Jupiter satellite events today, I'll keep this graphic up so you can sort of see what's happening when I read off the times. 242 UTC, the shadow of EO ingresses. At 312, EO begins its transitive Jupiter. At 352, the shadow of Europa ingresses. At 453 UTC, Europa begins its transitive Jupiter. At 5 hours UTC, the shadow of EO egresses. 529, the transitive EO ends. 647 UTC, the shadow of Europa egresses. 747 UTC, the transitive Europa ends. And all the way towards the end of the day at 2357 UTC, EO disappears into the shadow of Jupiter. So between 453 and 5 hours UTC, both EO and Europa and their shadows are on the face of Jupiter. And from 453 to 529, both EO and Europa are transiting Jupiter at the same time. And there are four satellite mutual events today, and that's the most mutual events that we've had since the 28th of December 2014. And again, I'll show the Earth Point of View. I realize these are a little dark, I'm still working on that a little bit. But as you can see, hopefully see, this point right in the center is the location of Jupiter at the zenith point at the time of the mutual event. And this first mutual event goes from 952 to 1017, and that's when Ganymede E. E. Colistow, this is a 24.4 minute event with an estimated magnitude flux drop of 0.194 magnitudes. It's a nice distance away from Jupiter, Colistow, that is, at 276.66 arc seconds from Jupiter, and Ganymede E. Colistow are 35.81 arc seconds apart. The next mutual event, oh, and as you can see from the Earth View here, most of North America will see this. Some in South America will see this, and folks over in Hawaii will also see this. The next event takes place at 1419, and goes to 1424 UTC, when Ganymede passes in front of Colistow. This is a 5.6 minute event, it's a very shallow grazing event with an estimated magnitude flux drop of 0.003 magnitudes. It is 308.91 arc seconds from Jupiter, and if you're in Australia and you may be able to see this, otherwise you have to pretty much be in the middle of the Pacific Ocean to see this one. Then it goes for the next one as well, which happens just a few minutes later at 1431 to 1441, and that's when Europa Eclipses EO. This is a 10.1 minute event with an estimated magnitude flux drop of 0.304. And the last satellite mutual event today also takes place pretty much over the Pacific Ocean, sort of maybe the Western Pacific Ocean, visible from Eastern Asia and some of Australia. And that takes place from 1528 to 1537 when Europa Occult EO is an 8.2 minute event with an estimated magnitude flux drop of 0.268. Okay, 24 hours of Jupiter sky. We're standing on the equator of Jupiter and looking out to the stars, and this is what we'll see over the next 24 hours. Jupiter's rotation is pretty fast, it goes around once on its axis about every 10 hours. So we see the sun a couple of times a day this way. It's fun watching some of the minor moons zipping around Jupiter and moving into its shadow and popping back out. And you can also see the four big, ghettily in moons as well. Earth is more or less hidden in the glare of the sun. And there was some new radio data taken on the 16th of January at the UT time shown here. And there were no new papers. So please subscribe and tell everybody you know about this podcast that I'm doing daily. And we'd like to hear your comments and suggestions and questions so you can send all of those and your images to the email shown. And until tomorrow, I bid you peace.
