We find a good match to the 03fg-like SN 2009dc before peak brightness, as well as good matches to SN 2000cx and the 00cx-like SN 2013bh between ~5 days before and ~7 days after peak. Additional followup is strongly encourgaed to better constrain the event's redshift and subclass. Classification performed using Next Generation Superfit (NGSF, Goldwasser et al. 2022). 2026TNSCR.369....1W
