report:
The error radius of GRB 051211a (Atteia et al, GCN4324) was observed with
Russian-Turkish 1.5-m telescope (RTT150, Bakyrlytepe, TUBITAK National Observatory,
Turkey), starting at Dec. 11, 18:38UT, i.e. ~15.8 hours after the burst.
Two frames (300s exposures in R and B bands) were taken. We did not detect
new sources to compare with DSS frames. Using USNO-B1 stars we estimate limiting
magnitude of our images as:
t-t0 Band m_lim
(hour) (mag)
