We observed the field of GRB 140311A (Racusin et al. GCN 15944) with the Nordic Optical Telescope (NOT) equipped with ALFOSC. 
The optical afterglow reported by Xu et al. (GCN 15947) and Klotz et al. (GCN 15952) is detected in the R band at 21.1 +/- 0.2 mag (calibrated against the USNOB1 catalogue) at t-t0=2.6 hours.
