We report the discovery and spectroscopic classification of three new supernovae from PTF (ATel #1964; http://www.astro.caltech.edu/ptf ). The supernovae were discovered by Oarical, an autonomous software framework of the PTF collaboration, based on observations made with the Palomar 48-inch Oschin Schmidt telescope. Spectroscopy was undertaken with the Double-Beam Spectrograph (DBSP; Oke \& Gunn 1982, PASP, 94, 586) on the Palomar 5-m Hale telescope on December 13 UT. The superfit (Howell et al. 2005, ApJ 634, 1190) program was used to determine the classifications.
