D Bersier, C. Guidorzi, A. Melandri, J. Jalpelj report:

The Faulkes Telescope South robotically observed GRB120521A (Swift trigger 
522586, Cumming et al, GCN 13305). The first exposure started approximately 240 
seconds after the trigger time.
Digital image subtraction does not reveal any variable source inside the XRT 
error circle. We find upper limits in R ~ 22.0 (40 minutes after the burst).
