reports on behalf of the Swift/UVOT team:
The Swift/UVOT observed the field of GRB 120802A starting 70 s
after the BAT trigger (Holland et al., 2012, GCNC 13555). Settled
observations started at 87 s. We do not detect any source inside the
UVOT-enhanced XRT error circle (Evans et al., 2012, GCNC 13558).
Preliminary magnitudes 3-sigma upper limits at this location for the
finding charts (FC) and the co-added images, are

The quoted magnitudes and upper limits have not been corrected for
the Galactic extinction along the line of sight to this burst of
E_{B-V} = 0.14 mag (Schlafly et al. 2011, ApJS, 737, 103).
