New Comet: P/2013 T2 (SCHWARTZ)

Cbet nr. 3676, issued on 2013, October 22, announces the discovery of a new comet (discovery magnitude ~18.8) by M. Schwartz on CCD images obtained with the 0.41-m f/3.75 Tenagra III astrograph. The new comet has been designated P/2013 T2 (SCHWARTZ).

We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 16 R-filtered exposures, 50-sec each, obtained remotely from MPC code F65 (Faulkes Telescope North) on 2013, October 16.4 through a 2.0-m f/10.0 Ritchey-Chretien + CCD (operated by Las Cumbres Observatory Global Telescope Network), shows that this object is a comet: sharp central condensation surrounded by a coma about 6" in diameter.

M.P.E.C. 2013-U18 (including prediscovery Catalina Sky Survey data from Sept. 14.4 UT, when the magnitude was given as 17.8-18.6) assigns the following elliptical orbital elements to comet P/2013 T2: T 2013 June 20.65; e= 0.53; Peri. = 342.52; q = 1.60;  Incl.= 9.36
