P J. Brown (Penn State) & D. Palmer (LANL)
on behalf of the Swift/UVOT team.
The Swift/UVOT began observing the field of GRB060505
(BAT Trigger=208654, Palmer et. al, GCN 5076) at
2006-05-05 20:58:30 UT, 14.37 hours after the BAT trigger.
The galaxy at the position of the first XRT source
(Conciatore et al GCN 5078) is detected in all 6 filters
but does not show significant variation, consistent with
Conciatore et al (GCN 5081).
No source is detected at the position of the second XRT
source (Conciatore et al GCN 5081) in coadded images with
any of the filters. The following 5-sigma magnitude
upper limits are not corrected for Galactic extinction.
Filter T_range(h) T_exp(s) 5sigmaUpperLimit(mag)
V 14.85-19.73 835 19.1
B 14.56-19.44 835 20.2
U 14.49-19.38 835 19.9
UVW1 14.37-19.32 1666 19.8
UVM2 14.92-19.85 1987 20.1
UVW2 14.62-19.67 3388 21.0
Where T_range is time post-trigger in hours, and T_exp
is the exposure time of the summed image in seconds.
