GEOPHYSICAL OBSERVATORY REPORTS, YEAR 1982 - NAGYCENK GEOPHYSICAL OBSERVATORY (Sopron, 1983)

1982

PREFACE The present Report of the Nagycenk Observatory is the 26. in the series. The first four were published in the periodical Acta Technica, the other in form of separate booklets. The reports have contained from the beginning data of the earth current recordings, with emphasis on the characterization of different period variations. This concerns also the geomagnetic recording which has been running since 1961. Since 1976, the recording oi Pel-type pulsations has also been operating with some interruptions. The observation network was supplemented in 1962 by records of the at­mospheric potential gradient and of the point discharge. Ionospheric absorption measurements have been operated since 1967. Exchange copies of these Reports can be obtained from the Geodetic and Geophysical Research Institute of the Hungarian Academy of Sciences (H—9401 Sopron, Pf. 5, Hungary) J. Somogyi Direktor
