Out of curiosity I looked into this a bit. North/South on the moon is pretty irrelevant for the objects orbit, but it struck at East 339 degrees (or West 21 degrees) near the Lubiniezky craters in the northwest part of Mare Nubium - which can be seen here - towards the center but a little bit in the south eastern part of the map.
and you can see the phase of the moon here. It changes slowly enough that a 24 hour range doesn't make a huge difference.

but apart from the crater looking roughly straight on, it's probably impossible to say the orbit it came from because the angle of approach is too big an unknown. It hit from kind of both the earth side and sun side direction, so it could have been a temporarily captured asteroid around the earth or a small comet or asteroid coming back from around the sun. Either could have made that impact I would think.
