We imaged the field of GRB 131127A detected
by SWIFT(trigger 00579571) with the robotic
telescope of (IAU station 565) Bassano Bresciano

Weather conditions were good.
We co-added a series of 5 exposures of 120 sec each.
We did not found any optical counterpart
in the error box of the XRTcandidate
(Markwardt et al., GCN 15516).
