Details:
Exactly one week ago, I captured a rather rare transit of Ganymede into the light interstice between Jupiter and its offset shadow:

Early this morning it happened again but this time the interstice was extremely narrow so it only lasted 16 minutes.
The sky was almost entirely covered with clouds and a strong wind was blowing so the circumstances were not very favorable.
But I managed to get Jupiter centered and focused some minutes before the appearance of Ganymede and did my best to catch the sequences.
Clouds were all the time passing in front of the planet and the wind made the telescope shake all the time.
It has been an awfull lot of job to put this animation together and even out the big differences in exposures but I had planned for this event from last year so I am still satisfied that I got it.
Telescope WO FLT 110 with a 2,5x Televue Powermate and a TIS DBK-41 camera.
Filmed between 03h10m and 03h33m UT.
