Availability of Geomagnetic Activity Indices

GeoForschungsZentrum (GFZ) Potsdam

Beginning January 1997, documentation, calculation and distribution of indices has moved to:

World Data Center for Geomagnetism Copenhagen

The unchanging reference:

Institut für Geophysik Göttingen

The original Göttingen internet server is still available. All scientific information on the WWW remains valid. The FTP server now mirrors the GFZ.
