Jamison Burke, Daichi Hiramatsu, D. Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Craig Pellegrino report/s a classification of object: SN 2021pfu
Type: SN IIRedshift: 0.015004
Remarks: The spectrum is dominated by narrow emission lines at the redshift of the host (z=0.015004; 1999PASP..111..438F; value from NED), with the primary other feature being Hα in a P Cygni profile. Assuming the redshift of the host, we measure a velocity of approximately 8,000 km/s for the absorption minimum of the Hα. Due to the presence of the Hα and the absence of a strong blue continuum, we classify this object as an old SN II.
