On the morning of September, 6 2010 I read in the YAHOU Minor Planet Mailing List MPML a live talk about the actual NEOs.
After testing the position of one of them, I could easily take some images of the object 2010 RF12 from my site.
Newest informations here: MPML #24172 and #24173  (September,8)

The asteroid is passing the Earth at September, 8  21:12UT in around 79.000 km distance. No impact will occur.
The body size is 6-14 meters in diameter. Here you find a Calculator for possible crater sizes and energy sums.

Discovered by Mt. Lemmon Survey at September, 5 2010
