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.
