Can anyone help me out. I am stumped. On the night of January 8th, around 11PM, I saw CLEARLY a satellite (moon) or its shadow just on the top edge of the southern belt of Jupiter. I watched it for a long time at the same time I saw a satellite just near the left side of Jupiter (I have a correct image scope)Maybe that satellite was casting a shadow.

BUT... When I consult my software programs about what moon it was they show NO moon or shadow at that time or at any time near that! Who's crazy? Me or the software programs? Does anybody have answer for what I saw that night? Thanks.

I have sometimes mistaken dark storms for satellite shadows. There's a few going around on Jupiter.

On the night of jan-8-03 beginning at 17:19 PST Ganymede began a transit and left the limb of jupiter at 20:38 PST. This was followed at 18:29 PST by a transit of Io which ended at 20:21 PST. The GRS was also just beginning at 18:29 PST. An occultation also took place on this night, Io And Ganymede. Several hours before and several hours after there were no other Galilean activities. The total event ended at 21:56 PST.

Could it be a matter of the UT date versus your local date?
