Several astrophotographers on BAUT have posted their pictures of 2007 TU24 as it tumbled past Earth last night. The pix are very cool. There are two ways in general to take them: let the ‘scope track the stars, and the asteroid will appear as a streak as it moves across the sky, or track the asteroid, which will look like a dot as the stars leave streaks.
Both methods were employed by various rock hunters, and the results are interesting. Go take a look!
I’ll have at least one more thing to say about this asteroid later, maybe Wednesday. I’d like the chance to talk about the actual science of it. There’s some nifty stuff going on.
