 We observed the field of Swift GRB 140518A (Melandri et al., GCN#16298)
with the 1.0 meter T100 telescope (Bakirlitepe, TUBITAK National
Observatory, Turkey), starting May, 18, 21:35:41 UT (~ 12.3 hours after the
trigger). 5 x 300 s exposures were obtained in the R filter under moderate
weather conditions.


We do not detect an optical afterglow within the reported XRT error circle
down to a limiting magnitude of >20.37 (2-sigma) in the combined R band
image.


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