Analysis of the light curves helps to estimate the shape and motion of each object and spectral measurements enable to discuss surface materials. We have made simultaneous observations at adjacent observatories. Bisei Spaceguard Center (BSGC) has 1.0-m/0.5-m telescopes to acquire light curves and the 101cm telescope with a low-resolution spectrograph has been used at Bisei Astronomical Observatory (BAO) located 100m from BSGC. The target objects are three GEO satellites located at around 140 deg E.: Japanese meteorological satellites HIMAWARI-8/9 (International Designator 2014-060A/2016-064A) and an Australian communication satellite SKY MUSTER (2015-054A). In this paper, we discuss photometric and spectroscopic characteristics and their temporal changes. Additionally, observations of another satellite QZS-3 (2017-048A) are scheduled in late September and it is possible to present supplemental data.","subitem_description_type":"Other"}]},"item_4_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_4_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_4_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA2130003019","subitem_description_type":"Other"}]},"item_4_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-21-001","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/00047767","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_4_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_4_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_4_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"日本スペースガード協会(JSGA)"},{"subitem_text_value":"日本スペースガード協会(JSGA)"},{"subitem_text_value":"日本スペースガード協会(JSGA)"},{"subitem_text_value":"日本スペースガード協会(JSGA)"}]},"item_4_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Spaceguard Association (JSGA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Spaceguard Association (JSGA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Spaceguard Association (JSGA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Spaceguard Association (JSGA)"}]},"item_4_version_type_30":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藤原, 智子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西山, 広太"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"奥村, 真一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"二村, 徳宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"FUJIWARA, Tomoko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NISHIYAMA, Kota","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKUMURA, Shinichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NIMURA, Tokuhiro","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":"2021-08-20"}],"displaytype":"detail","filename":"AA2130003019.pdf","filesize":[{"value":"12.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA2130003019.pdf","url":"https://jaxa.repo.nii.ac.jp/record/47780/files/AA2130003019.pdf"},"version_id":"238da213-ab63-46b5-a855-8d1e0c1b870d"}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Simultaneous Photometry and Spectroscopy of GEO Satellites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simultaneous Photometry and Spectroscopy of GEO Satellites","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["1891","2143","2144","2145"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-08-20"},"publish_date":"2021-08-20","publish_status":"0","recid":"47780","relation_version_is_last":true,"title":["Simultaneous Photometry and Spectroscopy of GEO Satellites"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:30:49.218879+00:00"}
