The PTF (ATEL #1964; http://www.astro.caltech.edu/ptf/ ) reports the discovery of a new supernova, PTF10jkx. The supernova was discovered by Oarical, an autonomous software framework of the PTF collaboration, on June 10 UT at RA(J2000) = 13:32:57.11 and DEC(J2000) = +48:18:54.5 at a magnitude of 19.8 in R-band (calibrated with respect to the USNO catalog) in the galaxy SDSS J133257.67+481855.7 (z=0.028). The supernova was not detected down to mag 21.5 in previous PTF images taken during May 2010 (3-sigma). A spectrum was obtained using the GMOS Spectrograph (Hook et al. 2004, PASP, 116, 425) on the Gemini North 8-m telescope on June 10 UT, revealing the supernova to be of type II. The superfit program (Howell et al. 2005, ApJ 634, 1190) finds a good match to the type II-P SN 1999em at 9 days post-peak.
