GCN Circular 15343
L. M. Z. Hagen (PSU) and K. L. Page (U. Leicester) report on behalf of the Swift/UVOT team: The Swift/UVOT began observations of the field of GRB 131011A starting 83.9 ks after the Fermi trigger 403206457 (Kasliwal et al., GCN 15324). No optical afterglow consistent with the PTF position is detected in the initial 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 w2 83920 97601 4896 >22.10 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.02 in the direction of the burst (Schlegel et al. 1998).
