Poznanski (UCB/LBNL) We report the discovery and spectroscopic classification of 11 new supernovae from the Palomar Transient Factory (ATel #1964 ; http://www.astro.caltech.edu/ptf ). The supernovae were discovered and classified by Oarical, an autonomous software framework of the PTF collaboration, as well as by Galaxy Zoo Supernovae (http://supernova.galaxyzoo.org), based on observations made with the Palomar 48-inch Oschin Schmidt telescope. Spectroscopy was undertaken with the R-C spectrograph mounted at the Cassegrain focus of the Mayall 4-m telescope at Kitt Peak Observatory on UT 2011 January 31 - February 3 by Ben-Ami, Matheson and Horesh. The superfit (Howell et al. 2005, ApJ 634, 1190) program was used to determine the classifications. Details of the discoveries are as follows:
