report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 110119A
67 s after the BAT trigger (Troja et al., GCN Circ. 11581). We find
a detection in the data consistent with the enhanced XRT position
(Evans et al., GCN Circ. 11582).
Preliminary 3-sigma upper limits using the UVOT photometric system
(Poole et al. 2008, MNRAS, 383, 627) for the first finding chart (FC)
exposure and subsequent exposures are:
Filter T_start(s) T_stop(s) Exp(s) Mag
white_FC 67 217 147 16.52 +- 0.03
u_FC 279 529 246 17.69 +- 0.09
u 279 529 246 17.69 +- 0.09
v 609 23078 1298 17.8 +- 0.7
b 535 29769 2006 16.5 +- 0.1
u 279 28857 1347 18.0 +- 0.4
w1 658 24777 990 >20.7
m2 5290 23984 1263 >21.0
w2 4880 18996 1165 >21.5
The values quoted above are not corrected for the Galactic extinction
due to the reddening of E(B-V) = 0.12 in the direction of the burst
(Schlegel et al. 1998).
