Jupiter's Four Moons

[ariane]

Hi All

Mike's transit animation reminded me of severla Jovian satellite alignments that I have attempted to observed over the last few months.

There is an was interesting alignment early this morning at 00:36. Jupiter and its four moons appeared as the figure attached. The four moons were very close to Jupiter, and Europa was transiting across the disk. Also Io and Callistro were above each other by about 0.8 Jovian diameters from the main planets disk.

Did anyone else see this?

The best event was on the 13th March at 09:24, with was invisible due to weather and Jupiter's position. This had, Io, Europa and Callisto in a vertical line above each other. The positions were as in the second Figure attached

Sadly, there are no other conjuctions like this for a little while.

Jup is never boring is it.
When I only had my ebay 60mm refractor, at the beginning of an observing session, I'd sketch where the moons were. After spending an hour or so on DSO's, I'd come back and see how far the moons had moved.
Good fun.

You must be keen to look at DSOs with 60mm. :thumbsup:

Three moons formed an awesome triangle last week, both mike and i tried to capture it, but it did not quite fit on the screen.

I tried capturing Ganymede, Europa and Callisto in the same field (away from Jupiter) last week but only ganymede and Europa fit in the 640x480 FOV of the webcam.

I caught the triple transit on Friday morning with Io coming out from behind Jupiter, and Ganymede and Europa in transit. Still processing!

It made me appreciate my 10" when I got it.;)

I saw Io Europa Ganymeade and Callisto all trailing Jupiter within the fov of my 12mm EP thursday morning last week. it was very very cool indeed. Altho i am not sure if they were actually in that order.....still its very very mesmurising to watch. made my day thats for sure.

On 22/3 at 4am AEST the moons were in order G E C I then Jupiter. At 6am Io was in front of Jupiter.
