larger GRB follow up collaboration report:
We observed the field of GRB060223b (Cummings et al. GCN 4821) in V-band
with the 60 cm telescope of peak Terskol observatory on Feb. 24 between
(UT) 02:24-02:41. No new source is detected in comparison of combined
image (18x60 s) with DSS2(R) at the refined XRT position (Perri et al. GCN
4835) and in a larger refined BAT position (Fenimore et al. GCN 4825).
The limiting magnitude is determined in comparison with USNO A2.0 (R):
