6586 2020-05-07 08:26:13 Daniel Perley Daniel Perley (LJMU), Cristina Barbarino, Jesper Sollerman, Tassilo Schweyer (Stockholm), Steve Schulze, Yi Yang (Weizmann) ZTF SN II 0.005224 2 ZTF Spectra were obtained with LT/SPRAT, NOT/ALFOSC, and P60/SEDM within 24 hours of discovery. 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. See our accompanying AstroNote for details. 2020TNSCR1259....1P

sn2020jfo

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
