The Nearby Supernova Factory reports the discovery of 11 new supernovae in images obtained from March 26 through April 22 UTC with the QUEST-II camera on the Palomar Oschin 48-inch telescope, operated by the Palomar-QUEST Consortium. R-band discovery magnitudes and J2000 coordinates are derived from comparison with the USNO-A2.0 catalog. A subsequent spectrum of each target (range 320-1000 nm), obtained with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-meter telescope, was used for classification.
