Cbet nr. 3122, issued on 2012, May 23, announces the discovery of a new comet (discovery magnitude 18.3) by A. R. Gibbs on CCD images taken with the Mount Lemmon 1.5-m reflector on May 21.3. The new comet has been designated P/2012 K3 (GIBBS).
We performed some follow-up measurements of this object, while it was still on the neocp. Stacking of eight R-filtered exposures, 60-sec each, obtained remotely, from the Siding Spring-Faulkes Telescope South on 2012, May 23.5, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows that this object is a comet: coma 5" in diameter and a tail nearly 5" long in PA 250 deg.
