Spectral classification with SNID favors a Type II-P supernova at redshift z = 0.012523, with the best-matching template being SN 2017pn (epoch 24.0 days).

Andrew Howell, Curtis McCully, Jake Ridenbaugh Global SN Project SN Ia 0.013 1 Global SN Project We report the classification of SN 2025ajmj as SN Ia. The spectrum shows a best match to SN Ia at approximately 7 days prior to peak light using SNID (Blondin & Tonry 2007, ApJ, 666, 1024). SNID finds a best-fit redshift of z~0.013.
