The oscillations exhibited dampedtype, quasi-sinusoidal oscillations. They were purely transverse and azimuthally polarized, indicating a toroidal mode oscillation. The characteristics of the pure toroidal mode oscillation were emphasized with a drastic change of the oscillation component of the magnetic field perturbation from the radial (V) to the azimuthal (D) direction in association with the SSC. The oscillations appeared as a harmonic structure in the frequency. The dominant harmonics were odd ones, i. e. 1st, 3rd, etc. Furthermore, the frequencies of the harmonics observed at each satellite showed a clear local time dependence. In conclusion, the present study verifies that the ULF waves in association with the SSC on March 23,1975 in the afternoonside of the magnetosphere behaved as a clear standing oscillation of toroidal mode of the field line resonance excited by the SSC.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","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, Tokai University/Department of Aeronautics and Astronautics, Tokai University/Department of Aeronautics and Astronautics, Tokai University/Department of Aeronautics and Astronautics, Tokai University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1984-07-01"}],"displaytype":"detail","filename":"KJ00000012221.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012221","url":"https://nipr.repo.nii.ac.jp/record/1588/files/KJ00000012221.pdf"},"version_id":"25a9810c-0fdc-4d14-8788-70f8186a1636"}]},"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":"A multi-satellite study of magnetic pulsations associated with a storm sudden commencement (SSC) as observed at syochronous orbit","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A multi-satellite study of magnetic pulsations associated with a storm sudden commencement (SSC) as observed at syochronous orbit","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["385"],"pubdate":{"attribute_name":"公開日","attribute_value":"1984-07-01"},"publish_date":"1984-07-01","publish_status":"0","recid":"1588","relation_version_is_last":true,"title":["A multi-satellite study of magnetic pulsations associated with a storm sudden commencement (SSC) as observed at syochronous orbit"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:56:07.559280+00:00"}
