The observation session\nbegan on 30 April 2025 at 17:52 UT, 21 minutes after the trigger.\n\n \n\nWe obtained multiple 180-second exposures using the Ic filter. An\nuncatalogued object is faintly visible at the location below, which could be\nthe optical afterglow:\n\nR.A. (J2000): 15:33:32.95 \n\nDec.
