The newly discovered object, officially designated 2011 CQ1, will make a close Earth approach today February 04, 2011 around 19:40UT at ~0.03(LD)/0.00008(AU) or 11855 km.2011 CQ1 has been discovered by R. A. Kowalski few hours ago in the course of the "Catalina Sky Survey" with a 0.68-m Schmidt + CCD. The object was moving at roughly 6 "/min and it was of magnitude ~19. According to its absolute magnitude H=32 this is a very small object, in the order of 4-5 meters.Just few hours after his discovery, we have been able to follow-up this object using remotely a 0.35-m f/3.8 reflector + CCD of "Tzec Maun Observatory" in New Mexico. At the moment of our images (on February 04.46), "2011 CQ1" was moving at 23"/min and its magnitude was ~18.Here you can see our image (stacking of 20 unfiltered exposures, 10 seconds each).

So no chance of an impact, but still _very_ close!!"The orbital element published here, are very interesting:2011 CQ1Perigee 2011 Feb 4.818749 TT = ...
