New Comet: C/2013 V3 (NEVSKI)

Cbet nr. 3695, issued on 2013, November 08, announces the discovery of a new comet (discovery magnitude ~15.1) by Vitali Nevski on four 180-s CCD exposures obtained on Nov. 7 with a 0.2-m f/1.5 reflector (and confirmed with images taken using a 0.4-m f/3 reflector) at the ISON-Kislovodsk observatory near Kislovodsk, Russia. The new comet has been designated C/2013 V3 (NEVSKI).

We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 19 unfiltered exposures, 30-sec each, obtained remotely from MPC code H06 (iTelescope, New Mexico) on 2013, November 07.3 through a 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer, shows that this object is a comet: diffuse coma about 18" in diameter elongated toward PA 275 deg.
