Eker (Akdeniz Univ.) report on behalf of a larger collaboration\n\n\n We observed the field of Swift GRB 140206A (Lien et al., GCN#15784) with\nthe 1.0 meter T100 telescope (Bakirlitepe, TUBITAK National Observatory,\nTurkey), starting February, 06, 16:33:24 UT (~ 9.268 hours after the\ntrigger). Observations were carried out in the R filter under good weather\nconditions. The afterglow is clearly detected in 300 s in the R band images\nat a position that is consistent with Oksanen et al. GCN#15786 and Oates et\nal., GCN#15787\n\nUsing USNO-B1 star USNO-B1 1567-0128093 (R.A.=9:41:23.33, Dec=+66:44:32.31)\nin the field, the magnitudes of the OT were estimated as follows;\n\nt-t0 (hr) exp.(s) filt mag err (+/-)\n\n9.590 300 R 18.65 0.05\n\n9.689 300 R 18.77 0.06\n\n9.788 300 R 18.75 0.06\n\n10.380 300 R 18.89 0.06\n\n Further observations using the same filter are ongoing.\n\nWe are grateful to TUBITAK National Observatory for prompt scheduling the\nobservations and technical support.",
