GCN Circular 5413
P. Schady (UCL-MSSL) reports on behalf of the Swift/UVOT team: The Swift/UVOT began observing the field of the GRB060805B on Aug. 7th at 01:34:52 UT. No optical afterglow candidate has been found in the coadded images of any of the UV/optical lenticular filters within the IPN error box reported by Hurley et al. (GCN 5407). The 3-sigma limiting magnitudes for the coadded images for the 6 filters are listed below: Filter Tstart (UT) Exposure(s) 3sig upper limits V 02:02:23 1397 20.56 B 01:45:13 1397 21.61 U 01:41:44 1397 21.26 UVW1 01:34:52 2802 20.77 UVM2 02:05:50 3619 21.27 UVW2 01:48:42 2402 21.27 These upper limits have not been corrected for the estimated Galactic reddening of E(B-V) = 0.037 mag (Schlegel et al. 1998).
