A. J. Blustin (UCL-MSSL), P. Schady (UCL-MSSL) and S. B. Pandey
(UCL-MSSL) report on behalf of the Swift/UVOT team:

The Swift/UVOT began observing the field of GRB 060602B at
23:56:01 on 2006-06-02, 87 s after the BAT trigger (Schady
et al., GCN 5200). No new source with respect to the DSS was
detected within the XRT error circle (Schady et al., GCN 5200)
in coadded images in any filter down to the following 3-sigma
magnitude upper limits:

Filter  T_range(s)  Exposure(s) 3sig_UL
V       193-29437   2320        20.2
B       670-18594   897         20.6
U       646-24379   1793        20.8
W1      622-23647   1998        20.1
M2      598-30163   2557        20.6
W2      699-28524   1110        20.3
White   87-6795     312         20.2

These upper limits are not corrected for Galactic extinction
(E(B-V) ~ 35.7; note that extinction estimates are unreliable
for Galactic latitudes < 5 deg).
