The discovery of AT 2023rve as a SN candidate has been reported to TNS by Mohammad Odeh and the spectroscopic classification as a type II SN has been reported to TNS by Claudio Balcon. SN 2023rve is located in the active galaxy NGC 1097 (Arp 077) at a redshift of z = 0.00424 (NED). We observed SN 2023rve with the Las Cumbres Observatory Global Telescope network (LCOGT) DeltaRho 350 telescope, equipped with a QHY600 CMOS camera, at McDonald Observatory on 2023-09-10 from 11:12:02 to 11:14:27 UTC at an airmass of 2.11 using the LCOGT SDSS filters
g', r', and i' and PanSTARRS zs and very short exposures (20, 20, 20, and 40 sec in g', r', i' and zs, respectively). We measure the following magnitudes, calibrated using the Gaia DR3 synthetic photometry catalog generated from the Gaia BP/RP mean spectra (Gaia Collaboration, 2022): g' = 14.51 +/- 0.03, r' = 14.51 +/- 0.03, i' = 14.55 +/- 0.06, and zs = 14.64 +/- 0.07.
SN 2023rve is currently the brightest SN in the sky. We encourage follow-up observations.
This work makes use of observations from the Las Cumbres Observatory global telescope network
and is based on observations made with the Las Cumbres Observatory’s education network telescopes
that were upgraded through generous support from the Gordon and Betty Moore Foundation.
These observations are part of a course in Astrophysical Techniques of the Master in Astrophysics
of the Astrophysics Department of the University of La Laguna and Instituto de Astrofísica de
Canarias (Tenerife, Spain). We thank David Bishop for his compilation of supernovae.
