4 Supernova Discoveries
The Nearby Supernova Factory reports the discovery of 4 supernovae in images
obtained Jul 13 through Jul 14 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).
