IMPACT ALERT: Japan's Kaguya will crash into the Moon on Wednesday, June 10th, around 1830 UT. The timing favors observers in Asia and Australia, who might be able to see a flash of light or a plume of debris rising from the Moon's southeastern limb. The spacecraft masses 2,600 kg and it will slam into the lunar surface at 6,000 km/hr. No one knows, however, how bright the flash might be or whether it will be visible even through large telescopes. Images of the crash, if any are captured, will be posted on http://spaceweather.com .
