Sharapov (MAO) on\nbehalf of larger GRB follow up collaboration report:\n\nWe observed error box of GRB061222a (Grupe et al., GCN 5954)  with Shajn\n2.6m telescope of CrAO. A set of  60 s exposures was taken on Dec. 22 in R\nbetween (UT) 18:28 - 19:29.   We do not detect afterglow registered in Ks\n(Cenko et al., GCN 5975, GCN 5978).  No object is also detected in refined\nXRT error box (Grupe, GCN 5966). Based on the USNO A2.0 star (23 53 02.73\n+46 32 18.50   17.60 R) we estimate 3 sigma limiting magnitude of a combined\nimage (48*60 s) as R=23.8.\n\nFinding chart can be found in\nhttp://grb.rssi.ru/GRB061222a/GRB061222a_R_ZTSh.GIF",
