Images taken by legendary comet and asteroid hunter Rob McNaught tonight using T17 in Spain.
Rob captured the NEO asteroid 2012 BX34 about 6 hours before closest approach using T17 in Spain while he was visiting the iTelescope HQ at Siding Spring Australia. Rob's data was used by the Goldstone Deep Space Communications Complex to obtain radar measurements to further refine BX34's shape, size and orbital parameters.
"Goldstone observations of 2012 BX34 are going well. The asteroid is so small
that we are barely resolving it even though we're imaging at a resolution of 3.75 meters.
Thank you to everyone who provided astrometry: it was invaluable!
Best wishes on behalf of the Goldstone radar team"
Its size was surprisingly small at approximately 5-8 meters in diameter and was only magnitude 16 in this GIF animation made from 10 x 2 second exposures. Image below was cropped.
Peter Lake used the New Mexico based T11 20" telescope to create this animation later on the same night.
