Akebono (EXOS-D) observations revealed that an electric field in the polar cap region was very irregular and an entire polar cap region was filled with many electron precipitation spikes when the interplanetary magnetic field (IMF) was directed north

Because of the importance of the balloon observations in the polar region, a project, Polar Patrol Balloon, is proposed in which a balloon will be able to float and observe around Antarctica for a month. In this project, the balloons are to be launch

Geomagnetic pulsations in the auroral zone through the plasma-pause were examined on the basis of IMS observation data obtained in Canada. It was shown that the geomagnetic pulsations in the daytime are reasonably accounted for in terms of HM waves p

SSC on 21st September 1977 is found to have given impact to VLF emission source in the magnetosphere and also to a power line system on the ground. A new feature of SSC effects to VLF emission was obtained on the basis of direction-finding technique

This paper describes the results of VLF observations made by the S-310JA-1 and 2 rockets launched on February 13, 1976 and February 10,1977 respectively. Both rockets were equipped with a dipole and a loop antenna which measured VLF plasma wave pheno

We present the first conjugate observations of subauroral ion drifts (SAID) in the magnetosphere (∼9000 km altitude) and ionosphere and coincident measurements by four ionospheric satellites. The parameters measured include ion drifts, energetic pr

We examine the spacecraft potential (SP) variations near the magnetopause. In the magnetosphere the Geotail satellite often observed transient SP increase accompanied by magnetic field enhancements. This signature (SP increase and magnetic field incr
