We note that although the spectrum is fit primarily to Ia 03fg-like events, the low S/N means that we are not currently confident in this sub-classification, additional observations are encouraged. Classification performed using Next Generation Superfit (NGSF, Goldwasser et al. 2022). 2026TNSCR.704....1W
