We report the discovery and spectroscopic classification of five 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 and by the users of Galaxy Zoo Supernovae, a citizen science project (http://supernova.galaxyzoo.org; Smith et al. 2010, arXiv 1011.2199), based on observations made with the Palomar 48-inch Oschin Schmidt telescope. Spectroscopy was undertaken with the Intermediate dispersion Spectrograph and Imaging System (ISIS) on the William Herschel 4.2-m telescope on November 30 UT (for PTF10aavz) and with the Double-Beam Spectrograph (DBSP; Oke \& Gunn 1982, PASP, 94, 586) on the Palomar 5-m Hale telescope on December 07 UT (for PTF10absf, PTF10abte, PTF10abui and PTF10abav). The superfit program (Howell et al. 2005, ApJ 634, 1190) was used to determine the supernova types. Details of the discoveries are as follows:
