report:
We continue our observations of the optical counterpart of GRB060526
(Campana et al. GCN 5162; French & Jelinek GCN 5165; Rykoff et al. GCN 5166)
with Russian-Turkish 1.5-m telescope (RTT150, Bakirlitepe,TUBITAK National
Observatory, Turkey). A series of frames were taken on May 30. The afterglow
is detected on combined images in both V and R bands.
We estimate the following Rc magnitudes for the OT:
t-t0 m_R err
104.05 23.14 0.09
Our Rc lightcurve can be found at:

In combination with MDM 1.3-m observations (Halpern et al., GCN 5188) these
data suggest that the OT light curve can not be fitted by a combination of
power laws and contain several optical flares.
