report on behalf of the Swift/UVOT team:
The Swift/UVOT began taking data on the field of GRB060413 at
2006-04-13T18:42:28, 124 s after the BAT trigger (Pagani et al.,
GCN 4957). No afterglow candidate was detected at the refined
XRT position (Pagani et al., GCN 4959) in summed images from
any of the filters down to the following three-sigma upper
limits.
Filter T_range(s) Exp(s) 3sig_UL
V 230-11744 1960 19.96
B 707-24977 2014 20.90
U 683-24287 2262 20.80
UVW1 660-23374 2118 20.14
UVM2 635-12648 1378 20.23
UVW2 735-7623 388 19.74
White 124-19078 1220 20.74
These upper limits are uncorrected for the estimated Galactic
reddening of E_{B-V} = 1.95 mag (Schlegel et al. 1998); we
estimate the V-band extinction A_v to be 6.24 magnitudes in this
direction.
