P. J. Brown & J. L. Racusin (PSU)
report on behalf of the Swift/UVOT team:
The Swift UVOT began taking settled exposures
on the field of the short hard GRB060801
(BAT Trigger #222154), 67 s after the BAT trigger
(Racusin et al., GCN Circ. 5378). No new source,
relative to the DSS, is seen inside the refined XRT
error circle (Racusin et al., GCN Circ. 5382) or at
the positions of the optical sources reported by
Castro-Tirado et al. (GCN Circ. 5384).
The 3-sigma upper limits for the first finding
charts and the coadded images are listed below.
Finding charts:
Filter T_range(s) Exposure (s) 3-sigma UL
White 67-166 100 19.9
V 173-572 400 19.5
Coadded images:
Filter T_range(s) Exposure (s) 3-sigma UL
White 67-7181 461 20.8
V 173-6309 1023 20.1
B 651-7127 412 20.6
U 627-6922 432 20.3
UVW1 603-6718 432 20.3
UVM2 579-6513 245 20.2
UVW2 679-6104 236 20.4
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) = 0.018 mag (Schlegel et
al. 1998).
