Memambetsu Magnetic Observatory

Premises of the Memambetsu Magnetic Observatory

     The history of the Memambetsu Magnetic Observatory dates back to the time of the Toyohara Magnetic Observatory, which was originally built in Sakhalin on the occasion of the Second International Polar Year (1932 – 1933) before being moved to Ikutora (Hokkaido) and finally to Memambetsu (Hokkaido) in 1949. Geoelectric and atmospheric electricity observations were started there in 1949 (atmospheric electricity observation was terminated in March 2011), and magnetic observations began in January 1952. The Memambetsu Magnetic Observatory was designated in 1967 as one of 14 such facilities worldwide to be involved in the determination of a geomagnetic activity index for the Northern Hemisphere (Kn).
