GCN Circular 12702
S. R .Oates (MSSL-UCL) and C. J. Saxton (MSSL-UCL) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of the IPN-detected burst: GRB 111215B, 31.5 hrs after the IPN trigger (Hurley et al. et al. GCN Circ. 12698) No optical afterglow consistent with the XRT position (Littlejohns et al. et al. GCN Circ. 12700) 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 u 113,256 130,435 4889 >21.4 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).
