Geomagnetic Filed Measurement with Antarctic Sounding Rockets in the Auroral Ionosphere (b. Electric Fields and Current System) (Proceeding of the Second Symposium on Coordinated Observations of the Ionosphere and Magnetosphere in the Polar Regions : Part I)
Geomagnetic field variations in the ionosphere were measured by the three axial fluxgate magnetometers on board the two sounding rockets, S-210JA-24 and 25,which were launched on August 17 and September 1, 1976 at Syowa Station, Antarctica, respectively. From the measured magnetic field data, It is...

| Summary: | Geomagnetic field variations in the ionosphere were measured by the three axial fluxgate magnetometers on board the two sounding rockets, S-210JA-24 and 25,which were launched on August 17 and September 1, 1976 at Syowa Station, Antarctica, respectively. From the measured magnetic field data, It is found that there are a large-scale horizontal current layer at 92-100 km and a local current layer at 113 km during the ascent of the S-210JA-24 rocket. Two small-scale current layers were measured at the height of 123 km during the descent of the S-210JA-25 rocket. And a large field variation was obtained at the heights between 88 and 108 km during the descent of the S-210JA-25 rocket |
