report:
We observed the field of the Swift-BAT GRB 081102 (Ukwatta et al.,
GCN8462) with Russian-Turkish 1.5-m telescope (RTT150, Bakirlitepe,
TUBITAK National Observatory, Turkey), starting at 03 Nov, 17:44 UT, i.e.
approximately 24.0 hours after the burst, using TFOSC CCD.
We made 3x300s exposures in R-band. We do not detect any new source inside
the XRT error circle (Osborne et al., GCN8467). Using USNO-B1 stars we
estimated the limiting magnitude of combined image as m_R ~ 22.
