Sunyaev (IKI)\n\nreport:\n\n    The error circle of GRB 060209 (Swift-BAT Trigger 180931,\nOsborne et al., GCN 4717) was  observed with Russian-Turkish\n1.5-m telescope (RTT150, Bakyrlytepe, TUBITAK National Observatory,\nTurkey) in R, starting on Feb. 09, 19:17 UT, i.e. ~8min after the burst.\n\n    A series of frames (2*60s, 9*100s exposures) were taken under bad \nweather conditions. We did not detect new source. Using USNO-B1 stars we \nestimate limiting magnitude of combined image as: R~20.3\n\nThis message may be cited.\n\n[GCN OPS NOTE(09dec06): The Subject-line was changed from \"060204\"\nto \"060209\" to match the contents of the Circular.]",
