report:

We observed the field of the short GRB 140606A (Stroh et al., GCNC 16353)
11.3 h after with the 6-meter BTA (+Scorpio-I) at SAO-RAS (Zelenchuk,
Russia). Comparison images (R-band) were obtained with the 1.5m telescope
at Observatorio de Sierra Nevada (south Spain) 60 h post burst. Within the
refined BAT gamma-ray burst error circle (Cummings et al., GCNC 16354), we
identify no variable object down to R = 22, in agreement with the limit
reported by Volnova et al. (GCNC 16371).
