U.Quadri, L.Strabla and R.Girelli report:
We imaged the field of GRB 131127A detected
by SWIFT(trigger 00579571) with the robotic
telescope of (IAU station 565) Bassano Bresciano
Observatory, Italy (www.osservatoriobassano.org).
The observations started 9h 2m. after the
GRB trigger,with our schmidt telescope
D=320/400 mm F/D=3.1.
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).
