The position\nof this OT is coincided with enhanced Swift-XRT position (Evans et al.,\nGCN CIRC 12813).\n\n      UT               T-T_GRB  Exp      mag      Tel    Filter\n\n2012-01-06 14:17:10     46      10   17.0+-0.3   East    P-\n2012-01-06 14:17:10     46      10     >16.8     West    P|\n2012-01-06 14:22:23    359      70     >18.0     East    P-\n2012-01-06 14:22:23    359      70     >18.0     West    P|\n2012-01-06 14:26:45    720     120     >18.2     East    P-\n2012-01-06 14:26:45    720     120     >18.2     West    P|\n2012-01-06 14:31:49   1024     180     >18.3     East    P-\n2012-01-06 14:31:49   1024     180     >18.4     West    P|\n\n\nThe images will be available at \nhttp://observ.pereplet.ru/images/GRB120106A/grb.html  .\nThe message may be cited.",
