Abstract (from CDS):

D. Wright, M. Fraser, R. Kotak, and S. J. Smartt, Queens's University, Belfast, report that a spectrum of PSN J23101271+3034426 = SN 2012fc, obtained on Sept. 21 with the 2.5-m Nordic Optical Telescope (+ ALFOSC; grism#4; range 320-910 nm; resolution 0.8 nm) on La Palma, is consistent with a very young type-II supernova. The continuum is blue, with superimposed broad P-Cyg features from H_alpha and He I. The lines are relatively weak, and the absorption troughs in the P-Cyg profiles are shallow, as is expected for a type-II supernova a few days after explosion. A fit using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) gives a match to several normal type-IIP supernovae such as 1999gi at about four days after explosion.
