Thanks DT! You beat me to that info. I will say though that though it may happen roughly 25 times a century, location plays a part. In 2008 you had to be in Europe or Africa for the best viewing and as Kelly Beaty states, the east coast of the US IF you are in the right location. So I would image though they may happen 25 times in this century, I may only have 3 or so opportunities to witness such an event so barring bad weather (which this year is no promise) I intend to see it even if it means traveling south.

Thanks, Kim

It's the end of the world as we know it.......... and I feel fine
Boy! Saturn with no rings, the Sun with no spots and now Jupiter's
satellites are going away.
Just who's running this solar system anyway?!?

Jim's post on viewing Jupiter and my own experience on Thursday night of watching Europa emerge from behind Jupiter reminded me that on the night of September 2nd and 3rd, of this year the Galilean moons will not be visible for around 2 hours. This last occurred on May 21st, 2008. According to this article from MSNBC:
"If you miss out seeing Jupiter without satellites, you can at least be consoled in knowing that there will be another, much better chance less than 16 months from now, on the night of September 2-3, 2009. That event will take place in the middle of the night for North America, with Jupiter appearing well up in the southern sky. And best of all, the four moons will be out of sight for almost two hours."
