20325 2025-02-07 02:10:09 Joseph Farah Joseph Farah (UCSB/LCO), Moira Andrews, Chris Ni, D. Andrew Howell, Curtis McCully, Kathryn Wynn None SN Ia 0.02635 1 We report the classification of AT 2025arb as a SN Ia (normal). Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe Ia several (~1-5) days prior to peak, with a particularly strong similarity to SN 2007co at -5 days. The supernova is visually located in WISEA J090759.42+411233.0 (z = 0.026350, d = 115.8 Mpc, value from NED). Additional followup is encouraged. 2025TNSCR.530....1F
