Rover 'O Rover, When Will the Asteroid Pass Over?

Late last month I was reading some articles about how there was an asteroid that had a 1 in 4 chance of hitting Mars on January 30th. Not that it'd be visible with small backyard scopes, I was hoping for a good show, perhaps on NASA TV or something, but reports from yesterday have nailed down the chances to 1 in 10,000. Bummer.  I remember the excitement when Shoemaker-Levy broke up and hit Jupiter, and granted this was one small asteroid, but it could have made an interesting crater and flash.
