Baltay, D. Rabinowitz, and A. Bauer, Yale University) reports the discovery of a supernova (mag approximately 17.8, calibrated to R) located at R.A. = 4h16m12s.37, Decl. = -13o13'11".6 (equinox 2000.0) in images obtained on Oct. 21.5 UT using the Quest II camera on the Palomar Oschin 1.2-m telescope as a part of the JPL Near-Earth Asteroid Tracking component of the Palomar Consortium. A spectrogram (range 320-1000 nm), obtained on Oct. 23.5 with the University of Hawaii 2.2-m telescope (+ Supernova Integral Field Spectrograph), shows the new object to be a type-II supernova at an approximate redshift of z = 0.03. The spectrum consists of a red continuum with obvious broad H-alpha in emission, along with He I 587.6-nm and Ca II infrared-triplet P-Cyg profiles. Comparison to a library of supernova spectra reveals a similarity to the spectrum of the type-IIb supernova 1993J at 18 days after core collapse (as estimated by Richmond et al. 1994, A.J. 107, 1022). A faint host galaxy is discernible on Digitized Sky Survey images below the (B about 21) limit of the USNO-B1 catalogue. Adopting z = 0.03 for the host, a low luminosity of M_B about -14.5 is derived for the host galaxy.
