TITLE: GCN CIRCULAR NUMBER: 12961 SUBJECT: GRB 120215A: Swift/UVOT Upper Limits DATE: 12/02/15 17:30:15 GMT FROM: Erik Hoversten at Swift/Penn State E. A. Hoversten (PSU) reports on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 120215A 110 s after the BAT trigger (Hoversten et al., GCN Circ. 12954). No optical afterglow consistent with the XRT position (Evans et al., GCN Circ. 12957) is detected in the initial UVOT exposures. The optical source reported by LaCluyze et al. (GCN Circ. 12956) was not seen in the first orbit of observations, however our upper limits are higher than their detections. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the first finding chart (FC) exposure and subsequent exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white_FC 110 260 147 >20.5 u_FC 322 572 246 >20.3 white 110 795 186 >20.8 v 652 672 19 >17.6 b 578 771 39 >19.2 u 322 746 265 >20.3 w1 702 721 19 >18.9 m2 677 869 39 >19.6 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.08 in the direction of the burst (Schlegel et al. 1998).
