1018 2017-05-27 15:25:22 David Bersier David Bersier None SN Ia-CSM 0.084 1 There is a strong emission line corresponding to Halpha at z=0.084. The best SNID fit is with SN 2002ic, a SN Ia-CSM, more than a month after maximum. From the spectrum, it is not clear whether the emission line is extended or not though. 2017TNSCR.601....1B
