SUPERNOVA 2005gm IN NGC 1423
       P. Luckas, Perth, W. Australia; O. Trondal, Oslo, Norway;
  and M. Schwartz, Patagonia, AZ, report the discovery of an apparent
  supernova (mag 18.0) on unfiltered CCD frames taken with the
  0.35-m telescope at Perth on Oct. 9.86 UT and the 0.81-m telescope
  at Patagonia on Oct. 12.38 in the course of the Tenagra Observatory
  Supernova Search.  SN 2005gm is located at R.A. = 3h42m39s.30, Decl.
  = -6o23'04".0 (equinox 2000.0), which is 12".5 west and 8".9 south
  of the center of NGC 1423 (which has position end figures 40s.14,
  22'55".1).  Nothing was visible at the position of 2005gm on an
  image taken by Schwartz on 2004 Oct. 16.31 (limiting magnitude about
  19.0) using the 0.81-m Tenagra telescope at Patagonia.

  SUPERNOVAE 2005gl AND 2005gm
      The "Nearby Supernova Factory" group (N. Blanc, S. Bongard, Y.

  Nucleaire de Lyon; P. Antilogus, G. Garavini, S. Gilles, R. Pain,

  Pecontal, Centre de Recherche Astronomique de Lyon; R. Kessler,
  Kavli Institute for Cosmological Physics, Chicago; and C. Baltay, D.
  Rabinowitz, and A. Bauer, Yale University) reports that a spectrum
  (range 320-1000 nm) of SN 2005gl (cf. IAUC 8615), obtained on Oct. 13.5
  UT with the Supernova Integral Field Spectrograph (SNIFS) on the
  University of Hawaii 2.2-m telescope, shows it to be a type-IIn
  supernova at a redshift of z = 0.016, consistent with that of the host
  galaxy NGC 266 (Huchra et al. 1999, Ap.J. Suppl. 121, 287, via NED).
  A spectrum of SN 2005gm (IAUC 8616), also obtained on Oct. 13.5 with
  SNIFS, reveals that it is a type-II supernova at an approximate
  redshift of z = 0.02, consistent with that of the host galaxy NGC 1423
  (Theureau et al. 2005, A.Ap. 430, 373, via NED); the spectrum is
  well-developed, exhibiting H-alpha, He I 587.6-nm features, and the
  Ca II infrared triplet in emission.
