The PTF (ATEL #1964; http://www.astro.caltech.edu/ptf/ ) reports the discovery of a new supernova, PTF10hif. The supernova was discovered and classified by Oarical, an autonomous software framework of the PTF collaboration, on May 16 UT at RA(J2000) = 17:09:47.15 and DEC(J2000) = +27:15:40.5 at a magnitude of 19.6 in R-band (calibrated with respect to the USNO catalog) in an anonymous host galaxy. The supernova was not detected down to mag 21.0 in previous PTF images taken during 2009 (3-sigma). A spectrum was obtained using the Double-Beam Spectrograph (DBSP; Oke \& Gunn 1982, PASP, 94, 586) on the Palomar 5-m Hale telescope on May 21 UT, revealing the supernova to be of type IIn, at z=0.141.
