NASA reports that a boulder has impacted the moon and it was big enough to have been seen by the naked eye if you happened to be looking at the moment of impact.  The flash as ten times brighter than any seen before. The 40 kilogram meteorite impacted at 56,000 mph with a force of 5 toms of TNT,  The same night many meteors were seen burning up in our own atmosphere that had the same trajectory. This impact could have been part of a larger event.

A few months ago a large meteor exploded over Russia injuring over a thousand people. Also there was another sighting which was visible to much of the eastern U.S. No injuries were reported from this event,
