Blondin (CNRS, LAM) adH0cc SN Ibn 0.038 1 adH0cc The spectrum is characterized by a blue continuum with subtle narrow He P-Cygni features superimposed, indicative of a Type Ibn supernova. The spectrum is similar to that of SN 2010al two days after maximum, although SN 2021jpk has less prominent features and a bluer continuum (see attached figure). Combined with the still-rising ZTF light curve this suggests that the supernova is a few days before or at maximum. We adopted the redshift of the host as the supernova redshift. 2021TNSCR1248....1T
