Аннотация:We present a new analysis of the secular variability in the longitudinal
magnetic field Bz of the roAp star γ Equ (HD 201601). Measurements of the magnetic field
Bz collected from the literature were combined with 33 new Bz measurements obtained
with the 6-m telescope of the SAO. All the available data cover a time that includes
the phases of both maximum and minimum Bz. We found that the period of the longterm
magnetic Bz variations is equal to P = (93Ѓ}3) yr, with Bz (max) = +593 G and
Bz (min) = −1133 G. Fitting the measurements with a double sine-wave function resulted
in two periods, P1 = 87.8 yr and P2 = 16.9 yr.
