Semi-diurnal peaks in the above geophysical parameters were found : these peaks occurred within a few hours before magnetic noon and others a few hours before magnetic midnight. A geophysical event which takes place in the day sector is called a D (day) event and night sector an N (night) event. The N event is similar to AKASOFU's substorm. One N event consists of three phases called N-1,N-2 and N-3. Early in the evening the N-1 is the major part of the N event. In mid-evening, three phases co-exist. The N-3 is the dominant feature of the late evening N event. Observations made by the Injun III satellite showed that VLF hiss (main feature of the N-1) was observed at the boundary and beyond the region of trapped electrons in the dark sector. VLF chorus (main feature of N-3) was observed in the closed lines of force. From the above observations, we suggest that the physical characteristics of auroral zone are asymmetric with respect to the day-night major axis. VLF hiss and band-type aurora are the main features of the evening side (N-1). VLF chorus, ionospheric absorption, ULF and patchy and surface-like aurora are characteristics of a post-midnight region (N-3). The break-up (N-2) is the transition between N-1 and N-3.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00246775","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Geophysical Institute, University of Tokyo"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1967-02-01"}],"displaytype":"detail","filename":"KJ00000000930.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000000930","url":"https://nipr.repo.nii.ac.jp/record/78/files/KJ00000000930.pdf"},"version_id":"ca7e663d-7a65-45db-b2a7-22b63ab397a7"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Auroral-Zone Geophysical Events and their Relationship to theMagnetosphere","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Auroral-Zone Geophysical Events and their Relationship to theMagnetosphere","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["25"],"pubdate":{"attribute_name":"公開日","attribute_value":"1967-02-01"},"publish_date":"1967-02-01","publish_status":"0","recid":"78","relation_version_is_last":true,"title":["Auroral-Zone Geophysical Events and their Relationship to theMagnetosphere"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T15:22:29.140346+00:00"}
