Yeah Bruce, I saw it a few times between breaks in clouds & it was pretty special! Managed to get a couple of short 5-sec AVIs about 10:30pm, but they were rough - seeing was poor, and the gusty wind was blowing the telescope around (Jupiter was really bouncing around, and it was a miracle Registax tracked it when I was processing). Anyway, I've attached what I did get (not great!) - I brightened the moons a little in Photoshop. They're identified in the file name. The grouping was a bit tighter earlier on, as you observed.
These groupings are well worth watching for. Sky Tonight has a good java script utility that you can use to predict moon events in advance.
