Ganymede
Using the Vixen ED 80mm (85x), I viewed through very turbulent air the transit (NOT occultation) of Ganymede last night. I lost sight of it 6.48pm. It disappeared in the extreme northern part of Jupiter. Clouds prevented me from viewing Ganymede's reappearance.

I later viewed (125x) Ganymede's shadow, which traveled across Jupiter, just inside the planet's northern limb.

I had a final look at 8.05pm. Using 20x, it was a interesting view with both Ganymede & Io being together just to the edge of Jupiter. The bright star Alpha Libra with its attractively named companion, Zubenelgenubi, were also visible in the same field.


Future events, which I will attempt to view:-
29/5 Io transit and shadow events.
30/5(around midnight) Callisto passes by Jupiter's northern pole.
