The Palomar Transient Factory (ATEL#1964) discovered eleven optical transients on UT 2009 Mar 17 in a R-band search of 498 sq deg (reference imaging was obtained prior to Mar 12). All transients were spectroscopically classified on UT 2009 Mar 20 by the Double Beam Spectrograph on the Palomar Hale telescope. The phase of the supernovae (days from maximum light) were identified by Superfit (Howell et al. 2005).
