Jupiter, Virgo, Spica, Comet 9/P Tempel 1 and Deep Impact
This coming Sunday night, at about 10:49 pm to 10:55 pm on the west coast, Mission Deep Impact will release a probe to crash into the comet to learn more about what makes it. This should be really exciting. It will be visible with as little as binoculars. Even better if you have a telescope. But don't worry if you are in a city, out of range or under cloudy skies - it will be telecast via TVs and online.
A couple resources online: NASA site. If you want to there is also a nice outline for how to host your own comet party. And NASA has their own channel on DISH and DirecTv. Check out their site at NASA TV.
Enjoy!
Oh yeah: The Impact is scheduled to occur at about 05:52 ±3min. UT 4 July 2005. (that means 10:52pm ±3 min on the west coast)
