Geophys. Res., 81, 2165, 1976a; J. Geophys. Res., 83, 599, 1978) spans 2-3° in magnetic latitude. Using the magnetic field data acquired with the EXOS-D satellite, we notice that sharp variations of magnetic field perturbation, showing the high current densities of several micro-amperes per squared meter at the ionospheric height, are included in the region 1 current zone. In this paper, we focus our analysis on a sharp gradient of magnetic field change within 1° in latitude. In the 20-04 MLT sector, the thin current sheet as an important part of the region 1 FAC system is often found to be just equatorward of the boundary FAC system (FuKUNism et al, J. Geophys. Res., 98, 11235, 1993). A statistical survey of more than 200 satellite's crossings of the region 1 zone (in the 17-05 MLT range) shows that about 60% of the identified region 1 current systems have the latitudinal structure of a thin (on average, 0.5°) current sheet with current intensity greater than one third of the total FAC intensity of the region 1 system.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006282","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":"AA11397422","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":"Department of Earth and Planetary Physics, University of Tokyo/Aichi College of Technology/Institute of Industrial Science, 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":"1999-09-01"}],"displaytype":"detail","filename":"KJ00000048022.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000048022","url":"https://nipr.repo.nii.ac.jp/record/6282/files/KJ00000048022.pdf"},"version_id":"e0f60053-89fa-46bd-970d-a0e5739007b7"}]},"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":"Latitudinal structure of the nightside region 1 field-aligned current observed from the EXOS-D satellite","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Latitudinal structure of the nightside region 1 field-aligned current observed from the EXOS-D satellite"}]},"item_type_id":"1","owner":"4","path":["803"],"pubdate":{"attribute_name":"公開日","attribute_value":"1999-09-01"},"publish_date":"1999-09-01","publish_status":"0","recid":"6282","relation_version_is_last":true,"title":["Latitudinal structure of the nightside region 1 field-aligned current observed from the EXOS-D satellite"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:03:36.233879+00:00"}
