We report the discovery and spectroscopic classification of 17 new supernovae from the Palomar Transient Factory (PTF; ). The supernovae were discovered and classified 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 R-C spectrograph mounted at the Cassegrain focus of the Mayall 4-m telescope at Kitt Peak Observatory on UT 2010 October 8-10 by Ben-Ami, Badenes, Kulkarni, and Matheson.

Details of the discoveries are as follows:
