David Bersier (LJMU) reports on behalf of the Liverpol GRB collaboration:

The Liverpool Telescope responded automatically to Swift trigger 522656
(Baumgartner et al, GCN 13318) 11 minutes after the trigger.

We do not detect any variable source inside the XRT error circle. A
representative upper limit is R=21.5 at 35 minutes after the burst,
calibrated with respect to USNO-B.
