Könyves-Tóth (Konkoly Observatory, Univ. of Szeged), R. Marques-Chaves (Univ. of Geneva), C. M. B. Omand (The Oskar Klein Centre), and R. Shirley (Univ. of Southampton) SGLF SN IIn 0.067 1 SGLF AT 2023erg (ZTF23aaecexq, ATLAS23ihs) was selected for LT SPRAT spectroscopy as a SLSN candidate using the ALeRCE ZTF light curve classification and our SGLF ZTF database and filters. However, the SPRAT spectrum shows that it is an SN II (likely an SN IIn) at z = 0.067 associated with a low luminosity host galaxy. The ZTF light curve is available at the ZTF/LSST brokers, e.g., Lasair https://lasair-ztf.lsst.ac.uk/objects/ZTF23aaecexq/ ALeRCE https://alerce.online/object/ZTF23aaecexq ANTARES https://antares.noirlab.edu/loci/ANT2023fxv5hcp12nzt and Fink https://fink-portal.org/ZTF23aaecexq.
