Cucchiara (NASA) report on\nbehalf of a larger collaboration:\n\nWe observed the GRB 221202A (Caputo et al., GCN 33005) field with the LCOGT\n1-meter Sinistro instrument at the South African Astronomical Observatory\nsite, on December 2, from 21:09 to 21:36 (corresponding to 1.05 to 1.5\nhours from the GRB trigger time) with the Bessel R and I filters.\n\nWe performed a series of 3x280s exposures in each band.  We do not detect\nany  sources in the XRT error region, in either band, consistent with other\noptical upper limits (de Wet et al., GCN 33007).\n\nThe following upper limits are calculated using the USNO-B.1 catalog as\nreference:\n\nR > 20.0\nI > 19.0\n\nThese magnitudes are not corrected for galactic extinction.",
