A. J. Blustin (UCL-MSSL), D. Fox (PSU), B. Hancock (UCL-MSSL),
T. Kennedy (UCL-MSSL), N. Gehrels (GSFC) on behalf of the
Swift/UVOT team report:
The Swift/UVOT began taking data on the field of GRB 060202 at
08:43:09 UT on 2006-02-02, 134 s after the BAT trigger (Fox et al.,
GCN 4629). No afterglow candidate is detected in summed images in
any filter within the refined XRT error circle (Morris et al., GCN
4632) down to the following 3-sigma magnitude upper limits.
Filter T_range(s) Exp(s) 3sigUL(mag)
V 134-1231 449 19.6
B 355-1025 419 20.5
U 656-4847 91 19.1
UVW1 633-4840 119 18.7
UVM2 608-4816 119 19.2
UVW2 561-4768 99 19.0
These magnitudes are uncorrected for Galactic extinction;
E(B-V) = 0.047. We note that the XRT position is 19 arcseconds
away from the nearest star in the DSS.
