Kotak, R. P. Breton, L. K. Nuttall, D. Pollacco, J. Casares Vel'azquez, A. Kumar, on behalf of GOTO collaboration report/s a classification of object: SN 2025advo
Type: SN IcRedshift: 0.014083
Remarks: Reasonable template matches to Type Ic SNe at the host redshift (0.014083, NED). We note that the GOTO light curve exhibits a significant pre-peak before the rise towards the main peak covered by ATLAS (see attached light curve).
The following Classification spectrum was provided:
Obsdate: 2025-11-26 03:53:43
Instrument: ALFOSC
Telescope: Nordic Optical Telescope
