Andrew Howell, Curtis McCully Global SN Project SN Ia-91T-like 0.016672 1 Global SN Project We report the classification of SN 2025ifq as SN Ia 91T-like. Spectrum resembles an overluminous Type Ia like 91T-like well before peak. The object redshift is acquired from the nearby host WISEA J101702.77-381623.3 (z = 0.016672, d = 78.27 Mpc, values from NED). Additional follow-up is encouraged. 2025TNSCR1539....1A
