I do not know whether the hobbying astronomers watched this or not, but NASA did notice a bright explosion on moon which was visible from the earth.
Explosion on the moon, reported by NASA May 17, was caused by a meteor hitting the surface and was visible on earth to the naked eye
"It exploded in a flash nearly 10 times as bright as anything we've ever seen before," said Bill Cooke, of NASA's Meteoroid Environment Office.
NASA's lunar monitoring program has detected hundreds of meteoroid impacts. The brightest, detected on March 17, 2013, in Mare Imbrium, is marked by the red square
However there is one question which may or may not have come to your mind. But if you're wondering how there can be an explosion on the moon, without oxygen, NASA has the answer for you. It says the flash of light comes not from any type of combustion - as we typically think of explosions - but rather by the glowing molten rock at the impact site.
So this is the answer which may add to your knowledge if you are a hobbying astronomer. So keep watch moon more - you may find another explosion too if you are lucky.
