The Nearby Supernova Factory reports the discovery of 8 new supernovae
in images obtained from April 27 through May 30 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.

SN 1998bw just before
peak brightness (Patat et al. 2001, ApJ vol. 555, pg. 900).
