Ramsay, on behalf of GOTO collaborationGOTOSN II0.025GOTOWe obtained a low-resolution spectrum of AT2020bgd (GOTO21Q) with the SPRAT spectrograph on the Liverpool Telescope on 2021 Jan 28.10 UT. The spectrum shows strong Halpha in emission at the host galaxy redshift of z = 0.025 superimposed on a relatively blue continuum. This is consistent with the object being a young Type II SN.2021TNSCR.269....1L
