Leonid meteors tonight and tomorrow night
The Leonids will be at their peak tonight and tomorrow, so go out and take a look (just dress warm). You won't be able to see anything before local midnight because of the geometry involved, so wait till after then. There's supposed to be impressive peak centered around 21:43 UT tomorrow; unfortunately, that's long before midnight for all points in North America, though if you're in Asia you'll have a good view, and the rest of us may still see some good stuff.
