In order to investigate characteristics of the occurrence, 138 SC events were analyzed using 1-second CNA and geomagnetic data at Syowa Station from April 1981 to December 1986. Local time dependence can be seen in the SC-associated CNA pulsation (CNA Psc). The occurrence rate is highest in the morning and has a secondary peak before midnight, that is to say, it shows a marked dawn-dusk asymmetry. CNA Psc accompanies geomagnetic Psc at the time of strong CNA increase caused by large SC's with high pre-SC AE index. Furthermore, CNA Psc tends to be more correlated with the H component of magnetic Psc in the Psc 5 period range and the D component for shorter period in the Psc 4 range.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004101","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":"Department of Physics,School of Liberal Arts, Asahi University/ National Institute of Polar Research/National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1991-06-01"}],"displaytype":"detail","filename":"KJ00000036032.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036032","url":"https://nipr.repo.nii.ac.jp/record/4101/files/KJ00000036032.pdf"},"version_id":"b4d680d4-be81-46c3-9af2-a45333643a6a"}]},"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":"CNA pulsations associated with geomagnetic sudden commencements","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CNA pulsations associated with geomagnetic sudden commencements"}]},"item_type_id":"1","owner":"4","path":["540"],"pubdate":{"attribute_name":"公開日","attribute_value":"1991-06-01"},"publish_date":"1991-06-01","publish_status":"0","recid":"4101","relation_version_is_last":true,"title":["CNA pulsations associated with geomagnetic sudden commencements"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:23:53.309256+00:00"}
