Jamison Burke (LCO/UCSB), Yael Dgani (TAU), Iair Arcavi, Daichi Hiramatsu (LCO/UCSB), D. Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino report/s a classification of object: SN 2020abbo
Type: SN IIRedshift: 0.017
Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe II at early times due to the blue continuum and faint broad Hα emission. The supernova is closest to UM 009 (z = 0.017000; 1991A&AS...91..285T:, value from NED). Adopting the distance modulus computed from this redshift (34.1), the r-band absolute magnitude of the object roughly coeval with the spectrum is -15.9 (apparent magnitude 18.2, from ZTF).
The following Classification spectrum was provided:
