 note = {P(論文), In July 1985 a joint Japanese-Danish-Norwegian balloon campaign for auroral zone conjugate observations (AZCO) was carried out. The campaign was complementing measurements at Japanese geophysical stations in Iceland and in Antarctica. The instrumentation on the ground included magnetometers, riometers, and VLF detectors in both conjugate areas and also back-scatter radar and auroral monitors in the South. The balloons were equipped with detectors for X rays, electric fields, and VLF electromagnetic emissions. This report is preliminary as the data have not been reduced thoroughly yet. Information has been obtained about particle injection during substorms and the connection between ionospheric electric and magnetic fields.},
