NED Abstract

Copyright by Central Bureau for Astronomical Telegrams. 2007CBET.1043A...1: Electronic Telegram No. 1043 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Nearby Supernova Factory Collaboration Supernovae 2007gx, 2007gy, 2007gz, 2007ha, 2007hb, 2007hc The "Nearby Supernova Factory" collaboration (G.

Birchall, Institute for Astronomy, University of Hawaii, Hilo; and J. Cough and J. Holtzman, New Mexico State University, Las Cruces) reports the discovery of six supernovae 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) were obtained for 2007gy, 2007gz, and 2007ha on Aug. 23.5 UT with the SuperNova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, yielding the spectral types and redshifts tabulated below; 2007ha was near maximum. Spectroscopy on Aug. 11.3 showed the spectrum of 2007gx to be similar to that of SN 1998bw. Spectra of 2007hb and 2007hc (which were not detected in images from Aug. 8 and 12, respectively) were obtained on Aug. 26.5. R-band discovery magnitudes and astrometry were derived from comparison with the USNO-B1.0 catalogue. SN 2007 UT R.A. (2000.0) Decl.
