larger collaboration


 We observed the field of Swift GRB 140629A (Lien et al., GCN#16477) with
the 1.0 meter T100 telescope (Bakirlitepe, TUBITAK National Observatory,
Turkey), starting June, 29, 18:42:13 UT (~ 4.412 hours after the trigger).
The afterglow is clearly detected in 300 s in the R band images.


Using USNO-B1 star USNO-B1 1318-0308023 (R.A.=248.99, Dec=+41.85) in the
field, the magnitudes of the OT were estimated as follows;

 We are grateful to TUBITAK National Observatory for prompt scheduling the
observations and technical support.
