Possible occultation of HIP 99314 and Ganymede We all are of course looking forward to see the great conjunction of Jupiter and Saturn. So I looked up the timeline of close approach in Stellarium and I saw that there might be an occultation with Ganymede and HIP 99314 (JD = 2459204.532313, date = 2020-12-21, 00:46:31 UTC). The star has a magnitude of around 7.5 and Ganymede has a magnitude of around 5.47 (combined magnitude is 5.31 -&gt; change in magnitude is 0.16), so it might be interesting to see the perceivable dim (maybe not with the naked eye, but maybe on camera). Unfortunately, I don't think that Stellarium is built with that precision, so I am asking your opinion about this situation.
There are 2 options:

Stellarium is built with that precision and this event is even more rare than previously thought.
Stellarium is wrong: there are other data that don't support its results.

Help is very appreciated, but let's hope for the best.
Thank you!
For what it's worth, I just got a shot of what looked like a 5th Galilean moon near Ganymede tonight (from South Florida). Here's a quick, unprocessed image. I thought I was going crazy seeing an extra moon (in the correct plane) that kept showing up. But looks like it's HIP 99314 (2nd dot to the upper left of Jupiter).
