Geomagnetic data for January 1976 : (AE (7) indices and stacked magnetograms)

"This IMS data report presents one of the most used types of ground-based data, i. e., analog records of geomagnetic variations. Also given are tables, graphs, and statistics from the preliminary derivation of AE indices based upon these records. It is anticipated that similar monthly data reports will be made available on an increasingly timely basis for the entire IMS observing period, January 1976-December 1979. As additional station records become available in time for processing, these will be added to later volumes in this series. in particular, we expect to have daily stacked plots of magnetograms from the North American meridional and longitudinal chains as well as the present selected Northern Hemisphere auroral zone station records used in the preliminary AE index derivation"-Introduction. by J.H.
