E. Klunko (ISTP), A. Pozanenko (IKI)  on behalf of larger GRB follow up
collaboration report:

We observed the error-box error box of GRB061019 (Guidorzi et al., GCN 5728)
with 1.5m telescope of Sayan Observatory (Mondy)  in R-bands on Oct.19
between (UT) 18:11 and 19:00. In a combined image (30 x 100 s) within
refined  XRT error circle (Guidorzi et al., GCN 5733) we do not found any
object down to limiting magnitude R~19.0 (3 sigma). The limiting magnitude
is based on USNO A2.0 catalog.
