Magnetic variations at conjugate points

Abstract

Magnetograms from Macquarie Island were compared with those from nine Alaskan IGY stations, Fort Churchill, Canada, and Cape Chelyuskin, USSR. The magnetic variations at Macquarie Island were found to correspond remarkably well in universal time with those at several Alaskan stations. On the basis of this study an area lying roughly between Healy and Kotzebue, Alaska, can be defined as the area conjugate magnetically to Macquarie Island.
