On Earth-Current Potentials at Memanbetsu, Ishigaki and Nemuro
Yokouchu, Y.
Abstract
Continuous registrations of earth-current potentials at Memambetsu,. Isigaki and Nemuro were carried out in June 1936，from September to October 1941 and from January to February 1943 respectively. The diurnal variation and some other observed facts are described and discussed，comparing those with the simultaneous observation at the Kakioka and the Toyohara Magnetic Observatories.
