New Comet: C/2014 Q3 (BORISOV)

Cbet nr. 3936, issued on 2014, August 24, announces the discovery of a comet (magnitude ~17) by G. Borisov (Observatory MARGO, Nauchnij) on CCD images obtained with a 0.3-m f/1.5 astrograph telescope on 2014, August 22.02. The new comet has been designated C/2014 Q3 (BORISOV).

We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 10 unfiltered exposures, 60-sec each, obtained remotely on 2014, August 23.4 from H06 (iTelescope network - Mayhill) through a 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer, shows that this object is a comet: coma about 7" in diameter elongated toward PA 215 (the comet was about +21 degree above the horizon at the moment of the imaging session).

M.P.E.C. 2014-Q38 assigns the following parabolic orbital elements to comet C/2014 Q3: T 2014 Nov. 19.24; e= 1.0; Peri. = 48.40; q = 1.63;  Incl.= 90.49

This is the third comet discovered by Gennady Borisov (previous were C/2013 N4 & C/2013 V2).

How bright will it get? I want to see it from my northern hemisphere observing location. It will be my 99th comet if I see it :)
