Honolulu (HON) Active

By Geomagnetism Program July 23, 2018

The Geomagnetism Program established an observatory at Honolulu in 1902, when the Program was part of the Coast and Geodetic Survey and under the leadership of Drs Louis A. Bauer and John A. Fleming. The present observatory site was established in 1960. The observatory is located at Ewa Beach at the former location of the Pacific Tsunami Warning Center of NOAA.

Honolulu Magnetic Observatory

Tucked in a grove of thorny mesquite trees, on an ancient coral reef on the south side of the Hawaiian island of Oahu, west of Pearl Harbor, a small unmanned observatory quietly records the Earth’s time-varying magnetic field. The Honolulu Magnetic Observatory is 1 of 14 that the U.S. Geological Survey Geomag­netism Program operates at various locations across the United States and its territories
