I know this is a little off topic but a asteroid the size of a football field will skim by earth (200,000 miles close) in about 1 hour. This is closer than the moon is to us and doesn't happen very often. The asteroid is darker than coal and can only be seen with a 6 in. or larger aperture telescope.
You can watch it here as it flies by ( http://events.slooh.com/ ). In an hour slews telecsopes will fire up and view the asteroid. This wont happen again until 2028, so consider this a rare opportunity!
(sorry for the short notice, its moving quite fast)
