Remarks: An optical spectrum of SN 2020yts, obtained on 2020 November 6 with the ESO Very Large Telescope UT1, the FORS2 spectrograph, and grism 300V, shows a blue continuum with prominent P-Cygni lines of hydrogen and helium superimposed. Based on the light curve, we estimate a phase of 9d after the explosion. The spectroscopic host-galaxy redshift has been taken from SDSS.
