report:
We observed field around position of optical counterpart (Perri et
al., GCN4487, Yost et al, GCN4488) of GRB060111B (Swift trigger 176918)
with Russian-Turkish 1.5-m telescope (RTT150, Bakyrlytepe, TUBITAK
National Observatory, Turkey), starting at Jan. 12, 02:11UT, i.e.
~5.9 hours after the burst.
A series of frames (13*300s exposures in R bands) were taken. We did
not detect OT, but detect an extended source on about 5 arcsec NW from OT
position with coordinates:
RA= 19h05m43.0s (J2000.0)
DEC=+70d22'29."8 (J2000.0)
Using USNO-B1 stars we estimate the following magnitude for this
source: R=20.52+/-0.03, and limiting magnitude of combined image as:
R~22.6
