We observed the field of OT (GCNs 3865, 3868, 3880) of GRB050824 (GCN
3866) with 1.5m telescope of Maidanak Astronomical Observatory. A set of R
images were taken between (UT) 21:27 - 22:01, on August 25.
We do not detect the OT in a stacked image. Based on USNO A2.0 nearby
stars we estimate limiting magnitude (3 sigma) of the stacked image (6x300
s) as R ~ 22.0. Detailed calibration of the stacked image is underway.
