Re: another potentially bright supernova 2020hvf in NGC 3643

Hi All,
Here is below my spectrum taken yesterday, 12 days after my first "shot". According to the calculation of PRISM, Sn2020hvf should have reached a mag of 12.88. And by comparison with the star just beside (Mag 13.19), Sn2020hvf should be more close than a Mag of 13.
According to Gelato, this spectrum fits well with a Sn1998bu after 9.5 days at Bmax; which is almost the same phase.
Also included, a comparison of my two spectrum.
cheers
Fred
