The PTF (ATEL #1964; http://www.astro.caltech.edu/ptf/) reports the discovery of PTF10yow (also discovered independently by LOSS as SN2010iq; IAUC 2493). The supernova was discovered by Oarical, an autonomous software framework of the PTF collaboration, on October 2 UT at RA(J2000) = 21:54:23.30 and DEC(J2000) = +15:09:20.7 at a magnitude of 18.5 in R-band (calibrated with respect to the USNO catalog) in the galaxy IC 5145 (z=0.0245). The supernova was not detected down to mag 20.9 in PTF images taken during the previous months (3-sigma). Spectra were obtained using the Double-Beam Spectrograph (DBSP; Oke & Gunn 1982, PASP, 94, 586) on the Palomar 5-m Hale Telescope on October 17 UT and the Intermediate dispersion Spectrograph and Imaging System (ISIS) on the 4.2-m William Herschel Telescope on October 31 UT, revealing the supernova to be of type Ic. The superfit program (Howell et al. 2005, ApJ 634, 1190) finds a good match to the type Ic SN 1995F.
