Study on the Solar Wind Energy Injection

磁层中的带电粒子被限制沿着磁场细线运动。因此，可以利用对半球极光事件的相似性来研究磁层磁力线的联系。在对共轭极光事件的早期研究之后，已经报道了在对半球仪器视野内最佳共轭点和非共轭活动点的可变位移。由于这些早期的工作，我们对极光在几代极光中的重要作用的理解有所提高。我们现在认识到，极光的共轭性可以反映极光电场、粒子加速、降水过程、太阳风-磁层相互作用以及地磁场的结构。最近。许多工作者正在研究极光共轭在极尖和极帽区域使用共轭数据。由于高纬度区域的磁场线从一个半球发出，在极尖/帽区，更多的离子与太阳风产生强烈的相互作用，特别是在白天，所以这是一个有趣的问题，从高纬度区域发出的磁场线可能连接到另一个半球或可能连接到行星际介质。近场线极光带内可见极光的共轭研究仍有许多未解决的问题。以往关于极光带的研究主要集中在极光形态的共轭和共轭区域内的位移。因此，极光共轭的重要物理特征尚未解决，例如极光活动、运动和变形的共轭仍然存在。为了研究南极Syowa站和冰岛3个站之间的可见极光与北极地区极尖/极帽极光耦合的未解决问题，我们进行了以下观测：1994年4月至5月：在冰岛Tjorness维修成像测速仪。1994年8月至9月：在冰岛的Husafell，用全天电视摄像机对可见极光进行共轭观测。在Husafell， Tjorness和Acdey维修仪器。1994年12月- 1995年1月：格陵兰岛3个站点的极地尖顶/帽可见极光观测。1995年2月至3月：在瑞典2个站进行立体观测。少

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.
