P. Schady (PSU/UCL-MSSL), A. Retter (PSU), P. Brown (PSU), D. Vanden. Berk
(PSU), F. Marshall (GSFC), N. Gehrels (GSFC) on behalf of the Swift/UVOT
team report:
The Swift/UVOT began taking data on the field of GRB 060203 at
00:45:26 UT on 2006-02-04, approximately 50mins after the BAT trigger (Retter
et al., GCN 4641). No afterglow candidate is detected in the summed images of
any filter, either within the refined XRT error circle (Morris et al., GCN
4651) or at the position reported by Malesani et al. (GCN 4645) down to the
following 3-sigma magnitude upper limits:
Filter T_range(s) Exp(s) 3sigUL(mag)
V 2976-27952 2618 20.7
B 5392-46016 4005 21.9
U 9808-51808 2952 21.4
UVW1 9600-51072 2516 20.7
UVM2 9392-50160 2829 21.0
UVW2 8976-34464 3816 21.4
White 8784-40240 3121 21.9
These magnitudes are uncorrected for Galactic extinction;
E(B-V) = 0.158.
