9388 2021-04-15 11:56:48 Charlotte Angus G. Dimitriadis, C. Angus YSE SN Ia 0.095 1 YSE Spectrum taken with SOAR/Goodman in on 13/04/2021. A sodium doublet places the transient at z=0.095, which makes the peak luminosity of the transient M~ -19.1. The luminosity, light curve evolution and broad (~9000km/s) silicon absorption point to SN Ia classification, approximately 5 days post-max based on the light curve. 2021TNSCR1224....1D
