The variability of the radial velocity of the cold Ap-star Gamma Equ = HD 201601 was studied with a time resolution of 2-4 minutes. Over a 40-min interval, 19 radial velocity estimates based on 161 line measurements were obtained. Radial velocity variations with an amplitude up to 2.8 km/s were recorded; periodicity was not detected in the 5-35 min range.
