Summary: | 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, the more northernly station. Amplitudes and occurrences of unstructured Pc 1-2 events tend to be greatest at Barrow. Inter-site comparisons are made for a complex, large-amplitude interval of Pc 1-2 activity which occurred on March 22-23, 1967. Comparisons of polarization sense at Barrow and College disclosed no meaningful relationship. Most structured Pc 1 events recorded at Kotzebue were also recorded at College, and vice versa, though some large-amplitude events appeared at only one site. The results of the experiment show the desirability for a still closer spacing between recording sites.
