U.Quadri, L.Strabla and R.Girelli report:
We imaged the field of GRB 131202A
with the robotic telescope of (IAU
station 565) Bassano Bresciano
Observatory, Italy (member of ISSP:
Italian Supernovae Search Project).
The observations started 88m. after the
GRB trigger,at the end of the twilight,
with our schmidt telescope
D=320/400 mm F/D=3.1.
Weather conditions were good.
We co-added 3 series of 20 unfiltered exposures
of 120 sec each.
We did not found any optical counterpart
in the error box of the XRTcandidate
(D. Kocevski et al, GCN 15559).
