From an analysis of some new spectroscopic observations of the magnetic CP star γ Equ we derived an effective magnetic field of -930±150G and a surface magnetic field of 4000G. The magnitude of the effective field is compatible with a variation of the field on a time scale of a little more than 70 years. The temporal behaviour of the magnetic field is explained by the superposition of a dipole and quadrupole and the model of the oblique rotator. Surprisingly a few radial velocity values differ from the expected ones by about 10km/s.
