report:
We observed the field around the position of the optical/IR counterpart
(Covino et al., GCN5234, Oates et al., GCN5243) of GRB060607 (Swift
trigger 213823) with the Russian-Turkish 1.5-m telescope (RTT150,
Bakirlitepe, TUBITAK National Observatory, Turkey), at the beginning
of June 08, about 19.77 hours after the burst. A series of frames was
taken in R band with TFOSC. The afterglow is not detected on combined
image with 1500s total exposure.

Using USNO-B1 star we estimate the limiting R magnitude
for the combined frame as R_lim~22.6
