Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino, Giacomo Terreran Global SN Project TDE 0.0482 1 2 Global SN Project Using Superfit (Howell et al. 2005, ApJ, 634, 1190) we find best fits to TDEs at declining phases. The spectrum shows narrow H at redshift z = 0.048 in agreement with the host redshift (WISEA J134315.65+191500.9, 2016SDSSD.C...0000:, value from NED) as well as broad H and He II 4686 lines at this redshift. This, along with the negligible host offset and the Superfit evaluation of the spectrum, indicate a likely TDE origin. Further followup is encouraged. 2023TNSCR1754....1N
