8262017-03-03 20:03:20mboquienMédéric Boquien, Dalya Baron, Lluís Galbany, Dovi PoznanskiSN IaWe fitted the spectrum to a library of template spectra using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). We find a best match to the Type Ia SN 2001G at +66d past maximum. Accounting for a rise time of about 20 days, this dates the explosion to the 2nd half of December 2015.
