in images obtained 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. 28.5 and 28.6 UT with the SuperNova Integral
Field Spectrograph on the University of Hawaii 2.2-m telescope show both
supernovae to be near maximum.  The R-band discovery magnitudes and
astrometry below were derived from comparison with the USNO-B1.0 catalogue.
