Very interesting observation of a dark mark on Jupiter... it's starting to ripple out across Twitter...

Would we be able to measure the temperatue and cross-referencing the decay with SL-9 data come up with a rough impact time? Which would then show us if it was the Earth-facing hemisphere or not - not that it would be a terribly useful piece of info.

Regarding a Saturn impact - two things:

1) It would probably be harder to spot by an amateur and thus more likely to be missed
2) I'm not sure Cassini could be retargeted so quickly anyway. It's running sequences preprogrammed weeks if not months ahead.

I'm sure that's true, but the fact that we're just two weeks from the 76th anniversary of film comedian Will Hay doing just that shouldn't go unremarked

The HST observations have begun...the first set wrapped up about four hours ago.
