Cucchiara (NASA) report on behalf of a larger collaboration:\n\nWe observed the Swift GRB 241115A field (Williams et al., GCN 38235)  with the LCOGT 1-meter Sinistro instrument at the South African Astronomical Observatory site, on November 15, from 21:52 to 22:24 UT (corresponding to 8.57 to 9.10 hours after the GRB trigger time) with the sdss r and i filters.\n\nWe performed a series of 3x300s exposures in i- and r-bands.  We do not detect a source within the Swift XRT error region in either band.\n\nThe following 5-sigma upper limits are calculated using the PanSTARRS catalog as reference:\n\nr > 21.5\ni > 21.2\n\nThese magnitudes are not corrected for galactic extinction.\n",
