Just missed us by three hundred thousand odd kilometers, luckily as no one saw it coming.

Here's an image of it taken from the BBC News article:

It's estimated that the meteor was about 0.5-1.5 metres across and weighed about 400 KG, about twice as much as a bubble car although its velocity was probably a tad higher.

I wonder what size crater it's left behind?

[kyokugaisha]

Ah, article says approx. a 40m crater. Bit too small for amateur scopes then.

Hopefully the LRO will be able to image it, it previously managed to get a picture of a smaller new crater.

Awesome! Apparently it was bright enough to see with the naked eye!
