report:

We observed the error box of GRB 050727 (Swift trigger No. 147918) with
Russian-Turkish 1.5-m telescope (RTT150, Bakyrlytepe, TUBITAK National
Observatory, Turkey). We made a set of 600s exposures in R, starting at
18:11 UT, July 27, i.e. about 11.7 hours after the burst.

We found no variable sources brighter than approximately R=22.5.
