name that moon...(Jupiter)

Hi all,

I was wondering if I could get some help figuring out which moons these are, if they are moons. Thanks in advance for your help.

Hello Andy,

you could go to this page

http://ringmaster.arc.nasa.gov/tools/viewer2_jup.html

and input the time of the shot (universal time) and fill out the other fields and it will let you download a post script file which will show you diagram telling you what they are. You may also need a post script viewer eg Ghostscript/Ghostview to read the file. There are probably easier ways but this works for me.

good luck

Andy -

The Jupiter timeline in Sky & Telescope is a handy quick reference too. But you'll need the time and date - Io moves pretty quickly.

Assuming you took this image the night of March 2, 2004 (05:10 on March 3rd, Universal Time) then the names from left to right are Europa, Ganymede, Callisto, Io.
