Average estimates by Achache et al. (1981) of the annual mean magnetic field components X, Y, and Z, over 10 West European observatories from 1953 to 1979 are analyzed. A 1970 jerk was fitted to the data using a least squares method, and the fit is compared to that of a polynomial having the same number of free parameters as the jerk (a quintic). The jerk and the quintic were both well fitted to the field component X. The jerk was better fitted to the Y component and the quintic was fitted better to Z. The jerk amplitudes of X and Z were closely related to the sunspot correction of Malin and Hodder (1982), and the sunspot corrections to Z and X were dependent on whether the core signal is taken as a jerk or a quintic. The prediction of Courtillot and Le Mouel (1982) that the jerk amplitudes of X, Y, and Z are proportional to their longitudinal derivatives was confirmed for the magnitudes, but not the signs.
