Burns (Carnegie) NUTS2 SN II 0.017 1 NUTS2, POISE 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. 2025TNSCR4076....1K

The spectral resolution is ~ 500, and the wavelength coverage is 4100-8500 A. We took the median of two spectra (unit in count) produced for each exposure of the SN by the KOOLS-IFU quick look system and that of five spectra of the standard star HD 93521 to perform flux calibration.
