R. Cartier, S. Points, J. Seron (CTIO) report/s a classification of object: SN 2020ga

Type: SN Ia
Redshift: 0.00917

The following Classification spectrum was provided:

Obsdate: 2020-01-07 08:48:21
Instrument: COSMOS
Telescope: CTIO - 4-m Victor M. Blanco Telescope

Remarks: The spectrum is consistent with a nearby SN Ia a few days before maximum heavily contaminated by host galaxy and with strong absorptions from Ca II H&K and Na D1 & D2 at the host galaxy redshift, indicative of significant host extinction in the line of sight. This is consistent with the SN being a nuclear transient. The reported distances to the host varies from 25 to 40 Mpc.
