During the last war the Telecommunications Laboratory of the Chalmers University of Technology, Gothenburg, started a small ionospheric observatory at Askim (57°14‘ N, 11°59‘ É) six miles south of the city. Fixed frequency recordings were begun in 1941 and a year later, in 1942, a semi auto- matic multi-frequency recorder was put in opera- tion. Already during the first years of operation of the Askim observatory, which unfortunately had to be very irregular during the war, a de- finite need was felt for a recording sister-observ- atory in the very north of Sweden where the auroral disturbances are much more frequent than at Gothenburg.DOI: 10.1111/j.2153-3490.1949.tb01276.x
