I opened up the small dome at 22:30. GOTO Jupiter got the planet in view with a 26 mm eyepiece─it didn't have far to move but nevertheless I feel that the GOTO system is now operating well.
A transit with shadow of Europa started just after 23:00 and I have a series of pictures starting just before the transit started and going on until half way. It didn't end until 01:20 and I felt disinclined to wait that long for a complete set. Preliminary processing indicates excellent images, so I am very pleased. Finally closed down about 01:00.
