C. Guidorzi (U. Ferrara), A. Gomboc (U. Ljubljana),
report on behalf of a large collaboration:

On 2010 August 02 at 05:51:53 UT the 2-m Liverpool
Telescope automatically began observing the Swift GRB 100802A
(Troja et al., GCN Circ. 11031) using the r' filter,
corresponding to 6.3 minutes after the burst trigger time.

We do not detect any uncatalogued source within the XRT
error circle. We do not detect the possible afterglow
candidate reported by UVOT either (Siegel and Troja,
GCN Circ. 11032) with the following upper limit:

Mid time from  Total Exp   Filter    Magnitude
trigger (s)    (s)
-------------------------------------------------
530            6x10        r' > 18.8
-------------------------------------------------

Magnitude has been calibrated from nearby USNOB1.0
R2 stars.
