9652 2021-05-14 21:34:06 Matthew Siebert M. R. Siebert, R. J. Foley (UCSC) UCSC SN II 0.013643 1 UCSC A further inspection of the new spectrum with the R400 grating on GMOS revealed that this is SN II. The spectrum is similar to early spectra of the type II SN 1999em. We measure an H-alpha absorption velocity of -10,200 km/s. 2021TNSCR1633....1S
