SUPERNOVAE 2007gl AND 2007gm
     The "Nearby Supernova Factory" collaboration (C. Baltay, A. Bauer, D.

Mexico State University, Las Cruces) reports the discovery of two supernovae
in images obtained on Aug. 3 and 5 UT using the QUEST-II camera on the
Palomar Oschin 1.2-m Schmidt telescope, operated by the Palomar-QUEST
Consortium.  Spectra (range 320-1000 nm) obtained on Aug. 6.6 and 6.4 with
the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m
telescope were used to classify each:  2007gl was around maximum, while
2007gm was a few months past maximum.  R-band discovery magnitudes and
astrometry were derived from comparison with the USNO-B1.0 catalogue.
