Rodriguez (NOIRLab/Gemini South), J.-E. Heo (NOIRLab/Gemini South), E. Sabbi (NOIRLab), R. Cartier (University of Antofagasta), S. Cikota (FER Zagreb, CAHA) None SN Ia 0.039 1 Pre peak (<~10 d). Best match in SNID is 91-bg-like at -6d, best visual match is 91T-like at -13d. Redshift from host as reported in NED (https://ned.ipac.caltech.edu/) . The spectrum shows a narrow emission at ~ 6073Å which we can associate with a hot pixel in the 2D spectrum. With and without that narrow emission the best match for the spectrum is SN Ia both in SNID and NGSF. Removing the narrow line results in a better match between the estimated spectral match redshift and the reported host redshift. 2026TNSCR.957....1P
