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. Details of the discoveries are as follows:
Name RA Dec Disc Date (UT) Disc Mag (r) Type z
PTF10aauo 09:59:54.26 +68:06:02.5 Nov 7 19.0 SN II 0.035
PTF10aauu 09:29:56.74 +35:21:52.6 Nov 13 18.8 SN II 0.044
PTF10acbu* 14:00:46.92 +59:20:16.5 Nov 15 18.1 SN Ic 0.009877
* Originally announced by Guoyou Sun and Xing Gao (CBET 2486) with a discovery date of Oct 03.605 UT (see also CBET 2600).
