While observing Jupiter tonight I saw that Europa and Ganymede were right beside each other from our perspective - they looked like a little double star floating near Jupiter! Very cool.

Here's my Celestron Omni AZ-102 telescope from earlier this evening. We were both patiently waiting for nightfall to arrive.

Doesn't look like my Canadiens are going to pull this one out. So I guess I'll cheer for the Hartford Whalers to win their second Stanley Cup! GO WHALERS!

Here's a better look at that active sunspot region that was just rotating into view day before yesterday. It's called AR4455 now. It just let off an M-flare, and the chances for stronger flares look pretty good. Maybe auroras at higher latitudes.
