The detection image was obtained on 2026-05-18 UT at the LCOGT node located at Cerro Tololo Inter-American Observatory using the SDSS-gp filter with a 180 s exposure. The transient is located at RA = 13:37:02.883, Dec = -29:51:56.911 (J2000). We performed photometric measurements and preliminary light-curve analysis, and comparison with previous archival images suggests that the source was not previously detected. 2026TNSTR2173....1J N
