46	2016-01-27 02:02:41	lgalbany	Lluís Galbany		SN II	0.014				From ATEL#8541: We report optical spectroscopy of the supernova candidate PSNJ 09195286-6854419. The spectrum (390-990nm) was obtained on UT 2016 Jan. 12.3 with the LDSS3 mounted to the Clay telescope at Las Campanas Observatory. The object is similar to that of a type-II supernova at a few weeks post-explosion, clearly showing H-alpha and H-beta absorptions and strong Fe lines characteristic of this SN type. Cross-correlation with a library of supernova spectra using SNID (Blondin & Tonry 2007, ApJ 666, 1024) gives a best match to SN 2006bp at +34 days since explosion. Correcting for the redshift of its host galaxy, PGC 26383 (0.011208), its expansion velocity is around 7780 km/s measured from the H-alpha absorption minimum.
