TNS Classification Report No. 22187 [ 2025TNSCR4076....1K ]
Date Received (UTC): 2025-10-11 10:36:58 Sender: Tom Killestein
Group: NUTS2
T. Killestein (Warwick), M. Stritzinger (Aarhus), T. Reynolds (NBI), C. Pfeffer (Hawaii), N. Morrell (LCO), C. R. Burns (Carnegie) report/s a classification of object: SN 2025yrt
Type: SN IIRedshift: 0.017
Remarks: Photometric follow-up by POISE using the 1-m Swope Telescope indicates that supernova 2025yrt reached a peak absolute g-band magnitude of −18.4 mag (corrected for Milky Way reddening) approximately 10 days after discovery. The source has since declined to −18 mag, consistent with the post-maximum behavior of a moderately luminous Type II supernova.
The following Classification spectrum was provided:
