The Nearby Supernova Factory reports the discovery of 23 supernovae in images obtained between March 26 and April 30 of 2007 using the QUEST II camera on the Palomar Oschin 48-inch telescope, operated by the Palomar-QUEST Consortium. Spectra (range 320-1000 nm) obtained with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-meter telescope were used to classify each. R-band discovery magnitudes and J2000.0 coordinates are derived from comparison with the USNO-A2.0 catalog. The following table summarizes the supernovae discovered (dates are UTC).
