TITLE: GCN CIRCULAR NUMBER: 16604 SUBJECT: GRB 140716A: Swift/UVOT Upper Limits DATE: 14/07/17 20:23:33 GMT FROM: Lea Hagen at PSU L. M. Z. Hagen (PSU) and K. L. Page (U. Leicester) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 140716A 34072 s after the BAT trigger (Cummings, GCN Circ. 16596). No optical afterglow consistent with the XRT candidate (Page, GCN Circ. 16600) or GROND candidate (Knust et al., GCN Circ. 16601) 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 (fc) 34072 34367 291 >19.17 u 40452 56904 1860 >20.20 v 40559 57641 1125 >19.52 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.131 in the direction of the burst (Schlegel et al. 1998).
