Image taken while this object was still mentioned on the PCCP of the Minor Planet Center before this object was assigned as comet C/2013 V2 (BORISOV).  Images taken by use of a remote telescope from the iTelescope.net network in New Mexico near Mayhill.  Data can you find in the image below.


CBET  nr. 3694: COMET C/2013 V2 (BORISOV)

     G. Borisov, Crimean Laboratory, Sternberg Astronomical Institute, reports the discovery of a comet with a coma diameter of about 16" on three CCD images taken with a 0.2-m f/1.5 astrograph on Nov. 6 (discovery observations tabulated below). .....


.... Erik Bryssinck (Kruibeke, Belgium) stacked seven 180-s unfiltered images obtained remotely with an iTelescope 0.25-m f/3.4 reflector near Mayhill that show an oval coma with a size of about 26" x 18", elongated toward p.a. 255 degrees; his follow-up images on Nov. 6.79 with an iTelescope instrument near Nerpio, Spain, shows a 25" x 20" coma elongated in p.a. 252 deg, noting that the dense star field made it difficult to detect the object easily.  Four stacked 60-s exposures taken by V. Nevski with a 0.4-m reflector at the ISON-Kislovodsk Observatory in Russia on Nov. 6.74 show a 15" coma.  Images taken by P. Bacci with ......
