I got a few positional images of this object with our 1.5-m (60") on Mt. Lemmon last night, but Jure Skvar? at the ?rni Vrh Observatory in Slovenia obtained one of the nicer time lapse animations of the asteroids motion against the background stars.

He writes on his Youtube page:

"The images for this animation were taken using a 60-cm telescope from
the ?rni Vrh Observatory on the night of 26 July 2011. Each exposure
was of 15 seconds. The telescope was tracking on the asteroid, changing the rate of tracking between exposures. The entire sequence lasted
about 4h40m, during which 635 exposures were made. At the time the
asteroid was less than 200000 km from Earth. At the closest approach
some 15 hours later the distance was about 20000 km."

4 hours, 40 minutes of imaging the NEO until his dawn, compressed down to 43 seconds. Enjoy
