The bright flash of a meteor impact was seen on the moon a couple of years ago on 17 March 2013. The flash was some 10 times any flash recorded before. NASA recorded the flash at lunar coordinates 20.6°N, 336.1°E.
The Lunar Reconnaissance Orbiter was able to image the location before and after and it turns out it has found a few more.
The video and a really cool before/after image is located at the NASA site.`
