Prior to the purchase of Alaska by the United States, the Russians operated a meteorological and magnetic observatory at Sitka from 1842 to 1867. The Geomagnetism Program established an observatory at Sitka, near the historic Russian cemetery, in 1901, 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 1940. The observatory is operated in partnership with the Bureau of Land Management (BLM).
