SUPERNOVA 2005gm IN NGC 1423\u00a0
\nP. 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.\u00a0 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).\u00a0 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.<\/p>\n

SUPERNOVAE 2005gm\u00a0
\nA 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
