Report of the geomagnetic and geoelectric observations, 1972 (rapid variations)

Results of observations of the Post-IGC, carried out by the Kakioka Magnetic Observatory in close cooperation with its two branch magnetic observatories, are presented. Standardization and comparison services of absolute magnetic instruments are operated by the electro-magnetic standard magnetometer A-56 and the proton procession magnetometer MO-P. Results of observations of rapid variations and records of the rapid-run induction magnetograms and rapid-run tellurigrams are included.
