Cucchiara (NASA) report on\nbehalf of a larger collaboration:\n\nWe observed the GRB 221115B (DeLaunay et al., GCN 32941) field with the\nLCOGT 1-meter Sinistro instrument at the South African Astronomical\nObservatory site, on November 16, from 19:40 to 20:08 (corresponding to\n34.15 to 34.62 hours from the GRB trigger time) with the SDSS r and i\nfilters.\n\nWe performed a series of 3x300s exposures in each band.  We do not detect\nany fading uncatalogued sources in the BAT error region, in either band,\nconsistent with other optical upper limits (de Wet et al., GCN 32943).\n\nThe following upper limits are calculated using the Pan-STARRS catalog as\nreference:\n\nr > 22.4\ni > 21.5\n\nThese magnitudes are not corrected for galactic extinction.",
