Holvorcem on CCD images obtained with the Tenagra II 0.41-m f/3.75 astrograph located near Nogales, AZ, U.S.A. After posting on the Minor Planet Center’s NEOCP webpage, this apparently asteroidal object as been found to show cometary features by our team.

The new comet has been designated COMET C/2013 G9 (TENAGRA).

M.P.E.C. 2013-H23 assigns the following preliminary parabolic orbital elements to comet C/2013 G9: T 2015 Jan. 24.08; e= 1.0; Peri. = 207.84; q = 5.17; Incl.= 145.90
