Solar- Flare Effect Type Variation in Geomagnetic Field at Kakioka , 1924-1951
Yokouchi, Y.
Abstract
Solar-flare effects (s.f.e.) in the geomagnetic field observed at Kakioka from February, 1924 to December, 1951 are tabulated. Times of beginning and ending (G.M .T.) on magneto-grams, their maximum deviations of declination，horizontal intensity and vertical intensity
denoted by Δ D. ΔH and ΔZ，respectively, and together with north-component ΔX， west-component ΔY and total force ΔF are given in the table 5. Some statistical results are given in the tables 1 - 4， and are shown in the figures 1 - 7. The present auther expresses his hearty thanks to Dr'. S. Imamiti who showed keen interest for this subject and gave him valuable guidance and criticism throughout the course of this work.
