TITLE: GCN CIRCULAR NUMBER: 8055 SUBJECT: GRB 080802: Swift/UVOT Upper Limits DATE: 08/08/03 05:56:21 GMT FROM: Patricia Schady at MSSL/Swift P. Schady (MSSL-UCL) and W.H. Baumgartner (GSFC/UMBC) report on behalf of the Swift/UVOT team: The Swift/UVOT observed the field of GRB 080802 starting 87 s after the BAT trigger (Baumgartner et al., GCN Circ. 8051). We do not find a source in any of the UVOT observations inside the XRT error circle (Baumgartner et al., GCN Circ. 8051). The 3-sigma upper limits for detecting a source in the first white and v finding charts (FC) exposure and co-added frames are: Filter T_start T_stop Exp Mag (3-sigma UL) (s) (s) (s) ========================================================= white (FC) 87 186 100 > 20.0 white 4803 5002 200 > 20.4 v (FC) 193 406 213 > 18.7 v 5214 5413 200 > 18.7 b 4598 6189 356 > 20.1 u 4393 6028 400 > 19.9 uvw1 4188 5822 400 > 19.8 uvm2 3983 5618 400 > 19.7 uvw2 5009 5208 200 > 19.5 The values quoted above are not corrected for the expected Galactic extinction corresponding to a reddening of E(B-V) = 0.80 mag in the direction of the burst (Schlegel et al. 1998).
