After the SLAS meeting last night several of us headed to SPOC to watch a few events involving three of Jupiter's Galilean satellites. In addition to all three of the observatory telescopes being open, Siegfried set up his 160mm refractor. We started off watching Io move out and away from Jupiter and it's shadow move across the planet. We then watched as Europa and Ganymede grew closer and closer. At closest approach they reminded me of a tiny snowman with one ball of "snow" on the bottom and a much smaller one on top. While I knew Ganymede is larger than Europa I'd never actually seen the difference. Having them so close together really made the difference apparent. Another thing that caught my eye was the difference in color. Europa was a brilliant white with maybe the slightest hint of blue and Ganymede a distinct shade of orange. Then came the event that generated the most excitement. Ganymede's shadow first touched Europa making the world look squashed sideways. Then, within minutes the 99% eclipse had Europa so deeply in shadow that it was invisible in all but the Grim scope and a minute or two later it was even invisible in the Grim. A few minutes later the rapidly moving shadow started to egress Europa and then, just as quickly as it had disappeared it regained it's previous brilliance. Quite a show! And, of course, being a SLAS event, ATS followed so we headed for Denny's in Tooele where we all got to exclaim about what we had seen. Many thanks to Bruce Grim for suggesting the event and to Siegfried Jachmann for setting it up. patrick
