New Comet: C/2013 G1 (KOWALSKI)

Cbet nr. 3454, issued on 2013, April 04, announces the discovery of a new comet (discovery magnitude ~18.5) by R. A. Kowalski on CCD images obtained with the Mount Lemmon 1.5-m reflector on April 02.4. The new comet has been designated C/2013 G1 (KOWALSKI).

We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 12 R-filtered exposures, 120-sec each, obtained remotely from Haleakala-Faulkes Telescope North on 2013, April 4.5, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows that this object is a comet with a tail nearly 12" long in PA 285 and a coma about 5" in diameter.
