Pozanenko (IKI) \nreport on behalf of larger GRB  follow-up collaboration:\n\nWe observed of  the field of  the Swift GRB 140215A (Markwardt et al.,  GCN \n15837)  with 0.4-m telescope of ISON-NM observatory starting on Feb., 15 \n(UT)  04:08:22, i.e 72 seconds after  Swift burst trigger.  We took 35 \nunfiltered images of 30 s exposures. We clearly detect the bright optical \nafterglow of GRB 140215A (Markwardt et al.,  GCN 15837; Cenko et al., GCN \n15838) in each separate image.  Coordinates of the optical afterglow \n(J2000) 06 56 35.83 +41 47 11.4 (uncertainties of 0.5 arcsec) coincide with \nOT coordinates (Markwardt et al.,  GCN 15837). Preliminary photometry  is \nfollowing:\n\nUT mid,      T0+        Filter    Exposure,  OT,    err OT\n                  mid                   s\n04:08:22      0.00101 none    30            13.60   0.03\n04:37:01      0.02090 none    30            16.46   0.20\n\nThe photometry  is based  on USNO-B1.0 nearby stars:\n\nN USNO-B1.0id RA                Dec           R2\n1 1318-0183851 06:56:13.01 +41:49:29.2 12.37\n2 1317-0181981 06:56:37.13 +41:44:34.4 14.39\n3 1317-0181986 06:56:38.48 +41:44:12.8 14.50\n\nThe power law index of  ~-1.2 of  our light curve starting from 0.0025 days \nand up to the end of our observations coincides with the index reported by \nPerley and Cenko  (GCN 15844).",
