The plural numbers of active region appeared on the solar surface. The most prominent one was the number 486, which yielded extremely large flares X17/4B at 0951UT on October 28, and X10/2B at 2037UT on October 29. These big flares hurled massive coronal mass ejections (CMEs) toward the earth. In this paper the solar-terrestrial relationship during the October super magnetic storms is discussed. Two fast moving clouds of gas from the sun swept the earth and sparked extreme geomagnetic storms producing the big ground magnetic field depressions of approximately - 350nT and - 400nT of Dst. Several interesting magnetic field variations observed in interplanetary space and their relationships to the ground magnetic field variations are discussed. Topics are as follows: 1) magnetic field polarity changes of the north-south component Bz of interplanetary magnetic field conveyed with the interplanetary coronal mass ejections (ICMEs) and their response to the magnetic field variations on the ground, 2) large amplitude tail flapping motions observed in the distant tail at about - 160Re, 3) large amplitude Pc 5 oscillations globally observed on the ground during the recovery phase of the super magnetic storm, and 4) large amplitude Pc 3 ULF waves observed in space from upstream through the magnetosheath to the dusk-side outer magnetosphere.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006399","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 Aeronautics and Astronautics, School of Engineering,/Department of Aeronautics and Astronautics, School of Engineering,"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2005-08-01"}],"displaytype":"detail","filename":"KJ00003376164.pdf","filesize":[{"value":"3.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00003376164","url":"https://nipr.repo.nii.ac.jp/record/6399/files/KJ00003376164.pdf"},"version_id":"9ac0d5ad-9c69-4a63-a958-5d1dcb51f4f9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"coronal mass ejection, interplanetary magnetic field, geomagnetic storm, MHD waves","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Extreme magnetic field variations during the October 2003 superstorm","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Extreme magnetic field variations during the October 2003 superstorm"}]},"item_type_id":"1","owner":"4","path":["809"],"pubdate":{"attribute_name":"公開日","attribute_value":"2005-08-01"},"publish_date":"2005-08-01","publish_status":"0","recid":"6399","relation_version_is_last":true,"title":["Extreme magnetic field variations during the October 2003 superstorm"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:02:01.287232+00:00"}
