7251 2020-07-30 07:08:55 Simon Prentice Simon Prentice, Kate Maguire, Mark Magee, Maxime Deckers (TCD) TCD SN I 0.016 1 TCD We find matches to Type Ia SNe about a week before maximum light using our Python based classification software and SNID (Blondin, S. & Tonry, J. L. 2007. ApJ, 666, 1024), but this is inconsistent with the absolute ATLAS-o magnitude of -16 mag. There does not appear to be significant reddening towards the source. Follow-up classification is encouraged. 2020TNSCR2341....1P
