Weiland (IfA, University of Hawaii), B. Stalder (LSST), A. Rest (STScI), D. E. Wright (University of Minnesota) Pan-STARRS SN Ia-91bg-like 0.044 1 Pan-STARRS Classifications were done using SNID (Blondin & Tonry 2007; 2007ApJ...666.1024B). The spectrum shows a good match with SN1991bg (Ia-91bg) at phase +2d, and infers a redshift of 0.037 +/- 0.007 from the spectral fitting. This is slightly closer than the redshift of the host galaxy of 0.044 (from NED), but within the uncertainty of the SNID estimate. We notice that the projection distance of SN 2021jvp is 28.6 Kpc away from the host centre at a remote location, if WISEA J142047.66-194744.9 is the host. There are no other plausible hosts visible in the vicinity. 2021TNSCR1306....1H
