The first one is the bright arcs which occur during strong northward IMF period. The second one is poleward leap arcs which occur during the recovery phase of a substorm. The third one is multiple faint arcs which occur during the strong northward IMF period and the fourth one is very faint sun-aligned arcs which occur during a magnetically quiet period. The first and the second polar cap arcs may be originated from the plasma sheet particles. On the other hand, the third and the fourth arcs may not be related to plasma sheet particles but magnetosheath particles. Although the first and the third arcs are seen during the period of a strong northward IMF, the magnitude of geomagnetic activity for the first one is larger than that for the third one. It seems that magnetospheric energy release may be also another important factor for the auroral dynamics.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004047","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756224","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":"Faculty of Technology, Takushoku University"},{"subitem_text_language":"en","subitem_text_value":"Geophysical Institute, University of Alaska"},{"subitem_text_language":"en","subitem_text_value":"Applied Physics Laboratory, Johns Hopkins University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1988-02-01"}],"displaytype":"detail","filename":"KJ00000035893.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035893","url":"https://nipr.repo.nii.ac.jp/record/4047/files/KJ00000035893.pdf"},"version_id":"4528a6ad-7d48-4bed-b520-a2e236e6bd36"}]},"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":"Polar cap arcs and their relationship to IMF and geomagnetic activity","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Polar cap arcs and their relationship to IMF and geomagnetic activity"}]},"item_type_id":"1","owner":"4","path":["537"],"pubdate":{"attribute_name":"公開日","attribute_value":"1988-02-01"},"publish_date":"1988-02-01","publish_status":"0","recid":"4047","relation_version_is_last":true,"title":["Polar cap arcs and their relationship to IMF and geomagnetic activity"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:24:32.059738+00:00"}
