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: AT 2025aaxf
Type: AGNRedshift: 0.037
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 2025aaxf is matched by an AGN spectrum, and its coordinates correspond to the ZTF target ZTF19aagzanb with a long variable light curve. The redshift is based on narrow H I and O III lines in the spectrum.
The following Classification spectrum was provided:
