Jupiter and a double shadow transit
Forecast said clouds after midnight, so the scope went out at nine and cooled for half an hour on the balcony.
Io and Europa shadows were both on the disc by 22:10. At 150x the pair looked like two pencil dots; at 200x seeing broke them up every few seconds, so most of the session stayed at 150x.

The Great Red Spot rotated into view near the end. Pale, more salmon than red this year.
