Description
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
