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).

Magnitudes were estimated with the USNO-B1 cat. 
and are not corrected for galactic dust extinction.
