I. Asfandyarov (MAO), A. Pozanenko (IKI), M. Ibrahimov (MAO) on behalf of
larger GRB follow up collaboration report:

We observed the field of GRB060717 (Sakamoto et al., GCN 5326) with 1.5 m
telescope of Maidanak Astronomical Observatory (MAO)  on July 17, (UT)
16:02 - 16:19. We do no detect optical sources in R-band within refined XRT
error box (Capalbi et al., GCN  5338). Based on USNO A2.0 we estimate
limiting (3 sigma) magnitude of a combined image:

Mid time T0+ (hrs), Exposure, R_lim

7.05                840 sec   20.9
