Discovered today!!! Only 8,800 miles from Earth!!

<SNIP>
Tomorrow, May 29, 2012 at about 07:07 UT, the asteroid designated 2012 KT42 will pass only ~14,100 km (8,800 miles) or about ~0.06 lunar distance (or 0.0001379 AU) above the Earth's surface. The asteroid was discovered by Mt. Lemmon Survey with a 1.5-m reflector + CCD on May 28, 2012 at magnitude ~18.1.
According to its absolute magnitude (H=28.8) this asteroid has an estimated size of roughly 3-10 meters, so it is a small object. We have been able to follow-up this object soon after his discovery while it was still on the neocp, from the Siding Spring-Faulkes Telescope South on 2012, May 28.4, through a 2.0-m f/10.0 Ritchey-Chretien + CCD.
At the moment of our images from FTS, "2012 KT42" was moving at about ~3.63 "/min and its magnitude was ~17.5. At the moment of its close approach around 07UT of tomorrow, 2012 KT42 will be bright as magnitude ~12.0 and moving at ~11021"/min.
