Abstract:

An objective method of inferring the polarity of the interplanetary magnetic field using the H-component at Godhavn is presented. The objectively inferred polarities are compared with a subjective index inferred earlier Svalgaard, 1972b. It is concluded that no significant difference exists between the two methods. The inferred polarities derived from Godhavn H is biased by the S sub q, sup p signature in the sense that during summer prolonged intervals of geomagnetic calm will result in inferred Away polarity regardless of the actual secor polarity. This bias does not significantly alter the large-scale structure of the inferred sector structure.
