We observed the field of the Swift GRB 141020A (Cenko et al., GCN

obtained several images on Oct. 23 starting on (UT) 14:25:05. At the
position of optical afterglow (Cenko et al., GCN 16928; Kuin et al., GCN
16932; Mazaeva et al., GCN 16943) we do not detect any object down to
R=23.0. Preliminary photometry is following:
