TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5138 SUBJECT: GRB 060515: Swift/UVOT Upper Limits DATE: 06/05/15 13:17:08 GMT FROM: Alice Breeveld at MSSL-UCL A. Breeveld (MSSL/UCL) and J. Cummings (GSFC) report on behalf of the Swift/UVOT team: The Swift UVOT began taking data on the field of GRB 060515, 3364s (including the 10s V settling exposure) after the trigger (trigger #210084). Swift did not slew immediately after the trigger because of an earth constrait (Cummings et al., GCN Circular 5132). At the position of the XRT error circle (Page and Kennea, GCN 5137) there are no new sources to the following 3 sigma upper limits: Filter T_range(s) Exp(s) 3sig_UL(mag) V 3364-11674 1062.4 20.1 B 4309-5893 347.0 20.4 U 4104-5735 393.3 20.2 UVW1 3900-5531 393.3 20.4 UVM2 3695-5326 393.3 20.7 UVW2 4718-10989 1082.2 21.4 White (160-650nm) 3384-10084 1179.9 20.9 These upper limits are uncorrected for the estimated Galactic reddening of E(B-V) = 0.03 mags.
