The focus of the present sutdy is the December 31,1985,event, when various types of disturbances occurred, including an outstanding disconnection event (DE)-like knot. Analysis of the Sakigake/IMF data reveals that comet Halley did not encounter the heliospheric neutral sheet on that day, demanding a new explanation for the DE-like event, different from the Niedner-Brandt model. During this event the comet encountered a high-speed solar wind stream from a coronal hole tongue of the sun. The event can be explained by a dynamic pressure model, according to which the DE-like plasmoid was caused by a sudden increase in the dynamic pressure of the solar wind. A result of a computer simulation is found to support this interpretation. The above-stated results were briefly reported already in Geophysical Research Letters. The present work is to report these in detail by separating these into three parts; I, II, and III. (Since different researchers contributed different parts in this detailed work, this is divided into the three parts.) In Part I, the heliospheric structure is obtained from the Sakigake/IMF observation.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166180000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-2853","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354474","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"東海大学工学部"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"東北大学理学部"},{"subitem_text_value":"名古屋大学空電研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"斎藤, 尚生"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"湯元, 清文"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平尾, 邦男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小山, 孝一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 富造"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中川, 朋子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小島, 正宣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Saito, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yumoto, Kiyohumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirao, Kunio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oyama, Ko-Ichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Itoh, Tomizo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakagawa, Tomoko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kojima, Masanobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0166180.pdf","filesize":[{"value":"859.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166180.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32693/files/SA0166180.pdf"},"version_id":"4ad5e914-3bdb-4ab6-837a-635d31d08ebb"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"HALLEY彗星のION TAILの擾乱とさきがけで観測された太陽風構造(I) : さきがけ磁場観測と太陽圏構造","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"HALLEY彗星のION TAILの擾乱とさきがけで観測された太陽風構造(I) : さきがけ磁場観測と太陽圏構造"}]},"item_type_id":"9","owner":"1","path":["1890","1911"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32693","relation_version_is_last":true,"title":["HALLEY彗星のION TAILの擾乱とさきがけで観測された太陽風構造(I) : さきがけ磁場観測と太陽圏構造"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:26:22.389024+00:00"}
