Residuals of astronomical observations of longitude and latitude in Asia may be related with the secular variations of the z-component of the internal geomagnetic field in the 1970's near the Southeast Asia (MizuNo 1984) . Variations of the internal field could be produced by convective motions in the fluid core. But heat transport from the fluid core into the mantle would not be enough to produce mantle plumes for a rapid variation. Local variations for periods of several years in longitude
