NASA's LCROSS Lunar probe made it's intentional lunar impact this morning. Below, you can see a video of the impact taken from the spacecraft itself. Unfortunately, the impact did not make a visible plume, as expected. Even the huge telescopes at Lick, Mauna Kea, and Palomar didn't observe a plume, so if you didn't see the plume, you didn't miss anything!
Some feed readers may have to click through to view the video.
One telescope, the MMTO at Mount Hopkins, Arizona, did capture a video of the impact, which although fuzzy, gets the idea across.
I'll post any more videos I find, but it looks like this might be it.
