2934	2018-10-31 14:27:58	Simon Prentice	S. J. Prentice, K. Maguire, S. J. Smartt (QUB)	None	SN Ia	0.027				SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) finds good matches to many SNe Ia shortly after maximum light. The best match is to SN 1991bg (albeit at z = 0.036) but further spectroscopic observations were unable to confirm this subtype.	2018TNSCR1657....1P
