Joint Analysis of Sastellite Data

奥斯特卫星由丹麦与美国宇航局合作发射，用于测量地磁场和高能带电粒子。这些数据被发布给研究计划得到奥斯特科学委员会批准的小组。该研究项目旨在加入奥斯特国际科学小组（OIST），并按照我们1995年批准的建议沿着开展地球高层大气电磁结构的研究。Oersted卫星的发射已多次推迟，现定于1998年夏季进行。因此，我们不能从卫星数据本身开始分析，但在以下几点上取得了很大进展. Pi 2地磁脉动自动探测和亚暴探测系统的研制;导出了快速观测的AE（极光电喷流）和Dst地磁指数，并在万维网主页上发布。促进SYM/ASY指数的推导，4.在万维网主页上显示快速磁图，5.通过与丹麦气象研究所建立镜像，促进地磁数据交换。这些成果必将有助于有效分析奥斯特卫星数据。加速AE指数的推导是负责推导的地磁和空间磁学京都大学数据分析中心的重要问题。该国际研究项目中与AE相关的部分是与另一个资助科研项目“改善俄罗斯AE台站地磁数据的采集和传输以及加速AE指数推导”（项目编号06554018）联合完成的。

The Oersted satellite is launched by Denmark in collaboration with NASA to measure geomagnetic field and high energy charged particles. The data are released to groups of which research proposal is approved by the Oersted Science Committee. The research project here aims to join the Oersted International Scientific Team (OIST)and to conduct studies on electromagnetic structure of the earth's upper atmosphere along our proposal approved in l995. It is another purpose to provide quick-look geomagnetic activity indices and magnetograms on line as the contribution from Japanese side to OIST.Launch of the Oersted satellite has been postponed several times and is now scheduled in summer of 1998. Therefore we can not start the analysis of the satellite data themselves but a great progress has been made in the following points.1. Development of the system for automatic detection of Pi2 geomagnetic pulsations and detection of substorms,2. Derivation of quick-look AE (Auroral Electrojet) and Dst geomagnettic indices and release on the WWW home Page,3. Promotion of derivation of SYM/ASY indices,4. Display of quick-look magnetograms on the WWW home page,5. Promotion of geomagnetic data exchange by mirroring with Danish Meteorological Institute.These achievements will certainly contribute to effective analyzes of the Oersted satellite data.Acceleration of derivation of the AE index is an important problem of Data Analysis Center of Geomagnetism and Space Magnetism Kyoto University which is responsible for the derivation. The AE related portion of this international research project has been done in association with another grant-in-aid scientific research project "Improvement of Acquisition and Transmission of Geomagnetic Data in Russian AE Stations and Acceleration of AE Index Derivation" (project No.06554018)
