Supernova 2005ly in UGC 934
Abstract
M. Modjaz, S. Blondin, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics; and T. Matheson, National Optical Astrononmy Observatory, report that a spectrum (range 350-740 nm) of SN 2005ly (cf. CBET 325), obtained by P. Berlind on Dec. 23.19 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-IIn supernova. The spectrum consists of a blue continuum, indicating young age, and Balmer emission lines with a narrow component with a velocity width of about 500 km/s (FWHM) superposed on a weaker and broader component with a velocity width of about 3000 km/s (FWHM), after removing the NED recession velocity of 10370 km/s for the host galaxy (from Falco et al. 1999, PASP 111, 438).
