CHARACTERISTICS OF PC-1 EVENTS OBSERVED AT KOTZEBUE, POINT BARROW AND COLLEGE, ALASKA
Induction magnetometer data recorded at three Alaskan sites over several years were studied with special attention given to Pc 1-2 micropulsation events. Amplitudes and occurrences of periodically-structured Pc 1 events were found to be significantly greater at Kotzebue and College than at Barrow, t...
