Emma Johtela, Uliana Pylypenko, Emily Sageser, Jouni Valkjärvi, Christina Humina, Tuomas Kangas, Erkki Kankare (University of Turku), Niko Pyykkinen (NOT) report/s a classification of object: SN 2025aaaa
Type: SN IIPRedshift: 0.026
Remarks: Classification was done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) as part of a remote observing course at the University of Turku. AT 2025aaaa is best matched with type IIP around the peak and the light curve also shows the target being in early plateau-phase. Redshift is from spectral match, which roughly matches the redshift of the broad Halpha emission line.
The following Classification spectrum was provided:
