 The algorithm for reduction of magnetovariational data acquired in a arbitrary reference system to the geomagnetic one is described. Such a reduction is needed if, for some reason, it is impossible to set  sensors correctly for data acquisition. The algorithm is based on spherical trigonometry formulas.
