Jouni Valkjärvi, Emma Johtela, Emily Sageser, Uliana Pylypenko, Tuomas Kangas, Christina Humina, Erkki Kankare (University of Turku), Niko Pyykkinen (NOT) report/s a classification of object: SN 2025aaoz
Type: SN IaRedshift: 0.089
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 2025aaoz is matched by a normal SN Ia around peak. An SDSS spectrum of its host galaxy (J074819.11+175622.2) returns a redshift of 0.089, consistent with the SNID fit.
The following Classification spectrum was provided:
