项目摘要

Charged particles in the magnetosphere are constrained to move along magnetic field fines. Thus the similarity of auroral events in opposite hemisphere can be used to investigate the linkage of the magnetospheric field lines. After the early studies of conjugate auroral events, variable displacements of the point of best conjugacy and non conjugacy activities within instrument field of view in the opposite hemisphere have been reported.Since these early work, our understanding of the important role in the generations of auroras has improved. We are now realized that the conjugecy of auroras may reflects the auroral electric fields, particle acceleration, precipitation processes, and solar windmagnetosphere interaction as well as the configurations of the geomagnetic fields. Recently. many workers are investigating the auroral conjugacy in the polar cusp and cap regions using conjugate data. Because the field lines emanating from one hemisphere at high latitude in the polar cusp/cap reg … More ion it make interaction strongly with solar wind especially in the dayside, so it is a interesting question that the field lines emanating from the high latitude region may connect to the other hemisphere or may connect to the interplanetary medium.There are still lots of unsolved problems for the conjugate study of visible auroras in the auroral zone in the close field lines. Previous works in the auroral zone were mainly concentrated with the conjugacy of auroral forms and displacements in the conjugate regions. Hence significant unsolved physical characteristics of the auroral conjugacy, such as the conjugacy of the auroral activity, movement, and deformation have been still remained.In order to study the unsolved prblems for the conjugacy of visible auroras between Syowa Station in Antarctica and 3 stations in Iceland and polar cusp/cap auroras in Arctic regions we carried out in the following observations ;April-May, 1994 : Maintenance of imaging riometer at Tjorness in Iceland.August-September, 1994 : Conjugate observation of visible auroras at Husafell in Iceland by all-sky TV cameras.Maintenance of instruments at Husafell, Tjorness and Acdey.December, 1994-January, 1995 : Polar cusp/cap visible auroral observations at 3 stations in Greenland.February-March, 1995 : Stereo observation at 2 stations in Sweden.

磁层中的带电粒子被限制沿着磁场细线移动。因此，对侧半球极光事件的相似性可用于研究磁层磁力线的联系。在对共轭极光事件进行早期研究之后，已经报道了对侧半球仪器视场内最佳共轭点和非共轭活动的可变位移。自从这些早期工作以来，我们对极光产生中重要作用的理解有所提高。我们现在认识到，极光的共轭可能反映了极光电场、粒子加速、降水过程、太阳风磁层相互作用以及地磁场的配置。最近。许多工作人员正在使用共轭数据研究极尖和帽区域的极光共轭。由于极地尖端/帽盖中高纬度一个半球发出的场线与太阳风相互作用强烈，特别是在白天，因此高纬度地区发出的场线可能连接到另一半球或可能连接到行星际介质是一个有趣的问题。极光区可见极光的共轭研究仍然有很多未解决的问题。近场线。以往关于极光区的工作主要集中在极光形态的共轭和共轭区域的位移。因此，极光共轭的重要物理特征，如极光活动、运动和形变的共轭，仍然存在尚未解决的问题。为了研究南极洲昭和站和冰岛3个站以及北极地区极尖极/冠极光之间可见极光共轭的未解决问题，我们进行了以下观测；1994 年 4 月至 5 月：维护冰岛特约内斯的成像测光仪。1994 年 8 月至 9 月：通过全天电视摄像机在冰岛的胡萨菲尔对可见极光进行共轭观测。胡萨菲尔、特约内斯和阿德伊的仪器维护。1994 年 12 月至 1995 年 1 月：极尖/帽可见极光观测位于 3 个车站格陵兰岛，1995 年 2 月至 3 月：瑞典 2 个观测站的立体观测。较少的
