M.P.E.C. 2013-E14, issued on 2013 March 04, reports the discovery of the asteroid 2013 ET (discovery magnitude 16.9) by Catalina Sky Survey (mpc code 703) on images taken on March 03.3 with a 0.68-m Schmidt + CCD. 2013 ET has an estimated size of 64 m - 140 m (based on the object's absolute magnitude H=23.1) and it will have a close approach with Earth at about 2.54 LD (Lunar Distances = ~384,000 kilometers) or 0.0065 AU (1 AU = ~150 million kilometers) at 1207 UT on March 09 2013. This asteroid will reach the peak magnitude ~15.0 on the first hours of March 09.We performed some follow-up measurements of this object on 2013, March 04.4, while it was still on the neocp, remotely from the Haleakala-Faulkes Telescope North, through a 2.0-m f/10.0 Ritchey-Chretien + CCD (Faulkes Telescope is operated by Las Cumbres Observatory Global Telescope Network). Below you can see our image, stack of 5X10-second exposures, taken with the asteroid at magnitude ~16.9 and moving at ~6.15"/min. At the moment of the close approach 2013 ET will move at ~ 153"/min.
