History of the Potsdam, Seddin and Niemegk Geomagnetic Observatories – Part 3: Niemegk

Abstract. The measurement series of the 3 geomagnetic observatories Potsdam, Seddin and Niemegk span over 130 years, starting in 1890. It is one of the longest, almost uninterrupted series of recordings of the Earth’s magnetic field. Data users frequently emphasize the high quality of the data and its significance for geomagnetic base research. Very well-known outstanding geomagnetism scientists as Max Eschenhagen, Adolf Schmidt, Julius Bartels, Gerhard Fanselau and Horst Wiese directed the observatories during their existence. This paper describes the history of the Niemegk Adolf Schmidt Observatory, which was started in 1932 and is currently further in operation.
