S. B. Pandey, M. J. Page, H.Z. Ziaeepour and S. R. Oates (UCL-MSSL)
report on behalf of the Swift/UVOT team:
The Swift/UVOT began observing the field of GRB 060805 at 04:49:25 UT,
79 s after the BAT trigger (Ziaeepour et al. GCN 5398). No optical
afterglow candidate has been found in the coadded images within the
XRT error circle (Ziaeepour et al. GCN 5398).
The 3-sigma limiting magnitudes for the coadded images for the
7 filters are listed below:
Filter T_range(s) Exposure(s) 3sig_Upper limit
WHITE 96-6633 511 20.1
V 79-11779 1583 20.3
B 680-6428 412 20.6
U 656-6223 432 20.2
W1 632-6019 432 19.7
M2 4182-12507 1105 20.6
W2 708-10866 1165 20.7
T_range is calculated from the time of the burst. These
upper limits have not been corrected for the estimated
Galactic reddening of E(B-V) = 0.024 mag (Schlegel et
al. 1998).
