TITLE: GCN CIRCULAR NUMBER: 12970 SUBJECT: GRB 120219A: Swift/UVOT Upper Limits DATE: 12/02/20 04:01:47 GMT FROM: Craig Swenson at PSU/Swift C. A. Swenson (PSU) reports on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 120219A 139 s after the BAT trigger (Swenson et al., GCN Circ. 12964). No optical afterglow consistent with the XRT position (Goad et al., GCN Circ. 12967) 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 first finding chart (FC) exposure and subsequent exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white_FC 139 289 147>21.2 u_FC 298 547 246>20.5 white 139 598 167>21.2 v 3846 4045 197>19.3 b 553 573 19>19.6 u 298 4614 397>20.7 w1 4255 4455 197>21.5 m2 4050 4250 197>19.9 w2 603 623 19>19.5 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.03 in the direction of the burst (Schlegel et al. 1998).
