The Nearby Supernova Factory (E. Pecontal and G. Rigaudier, Centre de Recherche Astronomique de Lyon; P. Antilogus, S. Gilles, R. Pain, and R.

Kessler, Kavli Institute for Cosmological Physics, Chicago; and C. Baltay, A. Bauer, D. Herrera, and D. Rabinowitz, Yale University) reports the discovery of 33 supernovae in images obtained during the months of October and November, using the QUEST-II camera on the Palomar Oschin 1.2-m Schmidt telescope. Those supernovae discovered on Oct. 26 October and Nov. 1 were found in SDSS i-band or r-band images taken in drift-scan mode as a part of the QUEST component of the Palomar-QUEST Consortium; the other supernovae were discovered in point-and-track mode as a part of the NEAT component (cf. CBET 263) of the same Consortium. Subsequent spectra (range 320-1000 nm) of each target, obtained with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, were used for classification of supernova types (as listed in the table below). Those type-Ia supernovae with z < 0.08 were all discovered at or after maximum; the supernovae with z > 0.08 include some that were discovered before maximum. The final column below gives the estimated time in weeks before (-) or after (+) maximum light for the type-Ia supernovae at the discovery date, based on the spectra; an "M" indicates that the object was within a few days of maximum at discovery; the three objects labelled "P" in this column had inadequate S/N to get a satisfactory phase, but they were clearly post-maximum. All magnitudes listed below are calibrated to the R band. ---------------------------------------------------------------------------— SN Date UT R.A. (2000.0) Decl.
