If a "globalkiller sized" 50 kilometer asteroid hit the moon on a clear dark night.

Would that look spectacular or what?

And how would that effect us here on Earth.
We would se the hit right,? BRIGHT FLASH,debree,??? 8)

It might have happened (http://www.bbc.co.uk/dna/h2g2/A993297) already, though there is significant disagreement over the testimony, and, if real, was probably much smaller than the impact you suggest.

I would guess that the flash would be as bright as the sun. Whatever it is, if a 50 km asteroid gets that close, we better start praying. :(

Imagine the Earth billions of years ago, impacts like this were common... It's a wonder how life formed so early.

I love speculating about these giant impacts. It seems like all of the attention is on the Chicxulub impact, and nothing goes to the bigger impacts that happened in the past with 50 km+ asteroids. I wish there was more information about this.

If you're willing to accept much smaller, there's a GIF video of a Leonid meteor striking the moon in 2001 here (http://skyandtelescope.com/news/archive/article_275_1.asp)

" meteoroids need only be between 4 and 20 centimeters across to make flashes visible from Earth."

I wold love it if the rovercams were still on remote and working,AND would film an impact on the surface.
Would there only be light or a fireball as well(no oxygen i know).
