After cross-correlating with a library of SN spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), I find best fit with SN IIP (2004et) at +1 day after maximum.

Analysis of the spectra using SNID (Blondin & Tonry 2007) shows a good match to SN 1999gi, a Type IIP SN, about 7 days before maximum light. We suggest that SN 2020jfo is a young Type II supernova.

hello,

here is a spectrum of SN2020jfo taken on 17/05/2020, near Lyon, France. Low resolution spectrum (R=500) with an Alpy spectroscope mounted on a Newtonian T250 f/4, and CCD Atik414ex,

kind regards,

Vincent Lecocq
