Ryotaro Koshi (The University of Tokyo), Ryuichi Hoshino (The University of Electro-Communications), Ichiro Takahashi (Tokyo Institute of Technology), Shigeyuki Sako (The University of Tokyo), Taiga Sasaoka (The University of Tokyo), Nozomu Tominaga (National Astronomical Observatory of Japan), Kenta Taguchi (Kyoto University) report/s the discovery of a new astronomical transient.
IAU Designation: SN 2024acn
Discoverer internal name: Tomo-e 202401aaayb
Coordinates (J2000): RA = 11:10:40.430 (167.668458) DEC = +21:06:27.76 (21.107711)
Discovery date: 2024-01-13 19:30:26.000 (JD=2460323.3128009)
Remarks: The nearest PS1 galaxy is PSO J167.6689+21.1073 (separation of 2.1 arcsec) with a photometric redshift of 0.180, which would imply an absolute magnitude of -22.1 mag if this were the host galaxy.
