The Nearby Supernova Factory reports the discovery of 2 supernovae in images obtained Jul 18 UTC 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-B1.0 catalog. The following table summarizes the discovered supernovae (dates are UTC).
