2802 2018-09-23 14:22:22 Simon Prentice S. J. Prentice, K. W. Smith (QUB) None SN Ia 0.108 1 Classification was attempted with both DASH (https://github.com/daniel-muthukrishna/astrodash) and Gelato (Harutyunyan et al., 2008, A&A, 488, 383), matches were found with SNe Ia a few days before maximum light at redshifts between 0.09 and 0.11. The best fit model of was 91T-like SN 1998es at z = 0.108 although confidence in this result is limited by the low S/N of the classification spectrum. 2018TNSCR1438....1P
