Two events are reported: one is a conjugate event, and the other is a nearly conjugate event. The conjugate event was observed at Narsarsuaq (magnetic latitude: 65.3\u00b0N), Greenland, at 0720\u20130820 UT (0506\u20130606 LT) on 17 February 2012. Analysis of the event revealed the following observational facts: (1) variation of parallel electron energy fluxes observed by THEMIS-E shows a correspondence to the auroral intensity variation, (2) plasma pressure and magnetic pressure fluctuate in antiphase with time scales of 5\u201320 min, and (3) perpendicular ion velocity is very small (less than 50 km/s). In the latter event, observed at Gakona, Alaska, on 2 February 2008, the THEMIS-D satellite passed across higher latitudes of finger-like structures. The data from THEMIS-D also showed the antiphase fluctuation between plasma pressure and magnetic pressure and the small perpendicular ion velocity. From these observations, we suggest that the finger-like structures are caused by a pressure-driven instability in the balance of plasma and magnetic pressures in the magnetosphere.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://doi.org/10.1002/2016JA023774"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/27068"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Geophysical Union"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2017 American Geophysical Union"}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2169-9402", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Katsuki, Nishi"}], "nameIdentifiers": [{"nameIdentifier": "73892", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kazuo, Shiokawa"}], "nameIdentifiers": [{"nameIdentifier": "73893", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Dennis, Fr\u00fchauf"}], "nameIdentifiers": [{"nameIdentifier": "73894", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-01-01"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Nishi_et_al-2017-Journal_of_Geophysical_Research-_Space_Physics.pdf", "filesize": [{"value": "21.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 21600000.0, "url": {"label": "Nishi_et_al-2017-Journal_of_Geophysical_Research-_Space_Physics.pdf \u30d5\u30a1\u30a4\u30eb\u516c\u958b\u65e5:2018/01/01", "url": "https://nagoya.repo.nii.ac.jp/record/24848/files/Nishi_et_al-2017-Journal_of_Geophysical_Research-_Space_Physics.pdf"}, "version_id": "0b303983-53e0-4742-a323-d083152e83c0"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Conjugate observation of auroral finger-like structures by ground-based all-sky cameras and THEMIS satellites", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Conjugate observation of auroral finger-like structures by ground-based all-sky cameras and THEMIS satellites"}]}, "item_type_id": "10", "owner": "1", "path": ["879/880/881"], "permalink_uri": "http://hdl.handle.net/2237/27068", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2017-11-07"}, "publish_date": "2017-11-07", "publish_status": "0", "recid": "24848", "relation": {}, "relation_version_is_last": true, "title": ["Conjugate observation of auroral finger-like structures by ground-based all-sky cameras and THEMIS satellites"], "weko_shared_id": null}
