collaboration:
We observed the field of GRB 140311A (Racusin et al., GCN 15944) with
AZT-33IK telescope of Mondy observatory on Mar. 12 and Mar. 13. Within
enhanced Swift-XRT error circle (Evans et al., GCN 15959) we do not
detect the optical afterglow (Xu et al., GCN 15947; Klotz et al., GCN
15952). Details of the photometry is following:
