I had an excellent view of the beginning of Europa's transit of Jupiter this evening. Since that moon is a dazzling bright white in color and since it crossed directly over Jupiter's Northern Tropical Belt, it was easily visible with my small scope. I normally can't see transits too well, but can usually see transit shadows.

After a solid week of pretty decent viewing the clouds have moved and an appear to be here to stay for the next 5 days or so. Bummer...I guess Ill just have to live vicariously through this message board.
Keep up the good work!

Yes, I observed it too. Even though the 66% illuminated Moon destroyed contrast due to the atmospheric glow from the 96% humidity I was dealing with last night, it was still a nice transit. I studied it unti it was around 25% across the planet.
On another subject, that same skyglow distroyed contrast while trying to view Mars hours later.

I got to see the shadow transit of Ganymede last night. It first appeared on Jove's disk at about the same latitude as Europa's transit of the previous night. Just at or above the Northern Tropical Belt.
I was treated to a few minutes of excellent seeing during this observing session, and saw excellent surface detail on Jupiter and Saturn. But then it went back to the usual boiling mush.
