report: 
 
We have observed the error box of GRB 050813 (GCN 3788 and GCN 3790)
with Russian-Turkish 1.5-m telescope (Bakyrlytepe, Turkey), using TFOSC
(the imaging and spectroscopic camera of the TUBITAK National
Observatory, Turkey). We made series of 60s exposures in R during UT
18:35 - 20:25, August 13, 2005.

We found almost all faint objects shown in GCN 3796 (Gorosabel et al.)
in our co-added image with limiting magnitude R ~= 23.
