Andrew Howell (UCSB/LCO), Curtis McCully (UCSB/LCO) None SN Ia 0.062 1 We report the classification of AT 2025dif as a SN Ia. Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe Ia at approximately peak light. The SN host may be WISEA J090909.21-130416.4, but no values for redshift are available in NED. SNID finds a best-fit redshift of 0.062. Additional follow-up is encouraged. 2025TNSCR.922....1F

Otherwise, the redshift is determined from the host galaxy. The observed spectrum is particularly red, and assuming a typical blue spectrum for a young SN, the color can be attributed to dust reddening of E(B-V) ~ 1.2 mag. The spectrum has broad spectral features consistent with that of a SN Ic-BL soon after peak brightness. The ATLAS light curve is either still rising or at peak, and so we caution that the phase reported is likely biased by ~7 days. Correcting for the derived reddening and a Hubble-flow distance accounting for Virgo inflow and the Great Attractor, we find an absolute magnitude of M_o = -19.0 mag, consistent with a SN Ic-BL before peak brightness. 2025TNSCR2130....1K
