Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Craig Pellegrino Global SN Project SN II 0.011625 1 Global SN Project The spectrum consists of a strong blue continuum with narrow host emission lines. As such, we classify it as a probable young SN II, although we note that at early times there can be confusion between young SNe II and young SNe Ib/c (see SN 2021yja classification reports). The B-band absolute magnitude approximately coeval with this spectrum is -16.0 (apparent magnitude 18.0, from LCO photometry). Further followup of this nearby rising source is recommended. 2021TNSCR3199....1B
