Global SN Project

The featureless blue continuum of this object suggests a young core-collapse SN. The primary feature is a narrow Hα emission line at the host redshift (z = 0.01503; 2003A&A...412...57P, values from NED): this could indicate the object is a SN IIn, but we note there is significant host contamination in the spectrum. The one day non-detection limit from ATLAS (AstroNote 2020-120) corroborates that the object is young. The B-band absolute magnitude roughly coeval with this spectrum is -16.1 and rising (apparent magnitude 18.2).
