GCN Circular 32390
A.A. Breeveld (UCL-MSSL) and N. J. Klingler (GSFC/UMBC/CRESTII) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 220710A 242493 s after the GECAM/GUANO trigger (Tohuvavohu et al., GCN Circ. 32375). No optical afterglow consistent with the XRT position (Beardmore et al. GCN Circ. 32385) is detected in the UVOT exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the initial exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white 242493 287404 4429 >22.9 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.030 in the direction of the burst (Schlegel et al. 1998).
