L. Tomasella, S. Benetti, E. Cappellaro, N. Elias-Rosa, A. Pastorello (INAF Osservatorio Astronomico di Padova) report/s a classification of object: SN 2020rvf

Type: SN Ic
Redshift: 0.022222

Remarks: The spectrum shows a red continuum and a very intense interstellar NaID (EW~0.72 nm) suggesting a high reddening (E(B-V)~1.2 mag, following Turatto, et al. 2003, fthp.conf, 200). The spectrum is contaminated by the host galaxy nuclear emission making it difficult to decide whether the narrow Halpha is indeed intrinsic to the SN. Assuming the high reddening, GELATO returns a good fit with the type Ic SN 1990aa spectrum 2-3 weeks after maximum but also with the peculiar SN 2002ic. The redshift is from RC3, via NED.

The following Classification spectrum was provided:
