Stritzinger (NUTSSN Ia0.016NUTSThe spectrum is relatively red, with strong lines dominated by the Ca NIR triplet, OI 7774, and SiII 6355. The minimum of the SiII line is at a velocity of 10,000 km/s. We were unable to obtain a good match to any supernova templates using SNID. The closest match to the SN using GELTAO appear to be 1991bg-like sub-luminous Type Ia SNe around maximum light, with possible additional HeI lines. The He line lines are at a somewhat lower velocity of 6500 km/s, compared to SiII. We note that the absolute magnitude of the transient at discovery is -16.1.
