Joint study on Polar Cap Disturbances Using AGO Network

极光和地磁扰动已经在极地帽区的自动地球物理观测站（AGO）进行了研究，那里没有人安装仪器来观察这些现象。我们研制了观测极光和地磁扰动的仪器，并与美国科学家进行了确证，在6个AGO台站进行了操作。活动如下。搜索线圈磁力计及光度计的发展我们制造了两台搜索线圈磁力计，以备在AGO台站使用的磁力计之用。我们还制作了数据采样率很高的光度计。搜索线圈磁力计和光度计的测试fukunishi， Takahashi和Fujito与斯坦福大学的一个小组在美国科罗拉多州的Yucca Ridge检查了磁力计和光度计。我们在AGO观测站观测极光和地磁扰动获得了良好的灵敏度。1995年10月，我们在南极洲的麦克默多站为AGO-5和AGO-6站设置了搜索线圈磁力计。1995年12月，Fukunishi和Takahashi访问了斯坦福大学，分析了AGO台站获得的极光、磁场和ELF-VLF波的数据。1996年12月，Fukunishi和Katsuyama再次访问斯坦福大学，详细分析AGO数据。1996年8月，福西访问英国南极实验室，分析AGO数据并进行讨论。奥格斯堡大学的engebretson教授访问日本东京大学，将他获得的磁通门磁强计数据与我们的搜索线圈磁强计数据进行比较。1996年8月，福西访问英国教堂大学，介绍我们的成果和未来的计划，并停留了一周。1996年12月，福石和胜山访问斯坦福大学，讨论未来的计划。我们从AGO数据的详细分析中发现了新的结果。其中一个有趣的结果是磁脉冲事件（MIE）和pc1爆发之间的相关性。我们与贝尔实验室的lanzerotti博士和奥格斯堡大学的engebretson教授一起详细分析了这些事件，他们指出了MIE和ELF-VLF波之间良好的相关性。6个AGO站的所有仪器仍然工作良好。我们正在用卫星和雷达数据调查我们的AGO数据。这些结果将为我们理解极帽现象提供更大的进展。少

Auroras and geomagnetic disturbances have been investigated at Automatic Geophysical Observatories (AGO) in the polar cap region where nobody had installed the instruments to observe those phenomena. We developed the instruments to observe auroras and geomagnetic disturbances and operated at 6 AGO stations with corroborations with scientists of the United States. The activities are as follows.1. Developments of search coil magnetometer and photometerWe made two search coil magnetometers for back up of magnetometers operated at AGO stations. We also made photometers with very high data sampling.2. Tests of search coil magnetometer and photometerFukunishi, Takahashi and Fujito checked magnetometers and photometers at Yucca Ridge of Colorado, USA with a group of Stanford University. We obtained good sensitivities to observe auroras and geomagnetic disturbances at AGO stations.3. Set up at AGO stationOn October, 1995, we set up our search coil magnetometers for AGO-5 and AGO-6 stations at … More MacMurdo station of Antarctica.4. Analyzes of AGO dataOn December, 1995, Fukunishi and Takahashi visited Stanford University to analyze the data of auroras, magnetic fields and ELF-VLF waves obtained at AGO stations. On December, 1996, Fukunishi and Katsuyama visited Stanford University again to analyze the AGO data in detail. Fukunishi visited Laboratory of Antarctica of UK to analyze the AGO data and to have discussions on August, 1996. Prof.Engebretson of Augsburg University visited Tohoky University to compare between his obtained flux gate magnetometer data and our search coil magnetometer data.5. Discussions of publication and future workFukunishi visited Church University of UK to present our results and future plan on August, 1996 and stayd for one week. Fukunishi and Katsuyama visited Stanford University to discuss future plan on December, 1996.We found new results from the detailed analyzes of AGO data. One of the interesting results is the correlations between magnetic impulse events (MIE) and Pc 1 bursts. We analyze the events in detail with Dr.Lanzerotti of Bell Laboratory and Prof.Engebretson of Augsburg University who indicates the good correlations between MIE and ELF-VLF waves. All instruments are still working well at 6 AGO stations. We are investigating our AGO data with satellite and radar data. Those results will provide us more large progress in understanding polar cap phenomena. Less
