1. Promotion of geomagnetic observation and data exchange.(1) Quasi-real-time data transfer from Huancayo observatory (Peru) has been started. Data transfer from Piura observatory (Peru) has also started.(2) Data transfer from Alibag observatory through Internet is improved. Real-time data transfer through GMS satellite is started in March 2001 from Alibag.(3) Large amount of high-time resolution geomagnetic data were supplied from French observatories.(4) A fluxgate magnetometer has been installed at Urumqi observatory in November 2000.(5) A GMS transmitter has been installed at Pevec observatory it Siberia.2. Results of the study on 3-dimensional current system.(1) The existence of the net Birkeland currents which flow into the ionosphere on the day side and flow out on the night side has been confirmed from the analysis of the data obtained by the Oersted satellite. The inter-hemispheric field-aligned currents are also detected from the analysis.(2) From the analysis of mid-latitude geomasnetic field data, a seasonal dependence of the net Birkeland current system was found.(3) The high-correlation among the AE, ap and ASY indices was interpreted as a common manifestation of the effect from the current system.3. Polar HF radar data analysisThe polar F-region ionospheric irregularities have been studied with the data obtained by the SuperDARN HF radar network. A statistical distribution of the occurrence distribution of the irregularities and the mechanism has been discussed.

1.促进地磁观测和数据交流。(1)已开始从万卡约观测站（秘鲁）进行准实时数据传输。来自皮乌拉观测站（秘鲁）的数据传输也已开始。(2)改进了通过互联网从Alibag观测站传输数据的工作。2001年3月开始从Alibag通过GMS卫星进行实时数据传输。(3)法国天文台提供了大量高时间分辨率的地磁数据。(4)2000年11月在乌鲁木齐天文台安装了磁通门磁力仪。(5)在西伯利亚的Pevec天文台安装了一台GMS发射机。三维水流系统的研究结果。(1)从Oersted卫星获得的数据的分析中，证实了在日侧流入电离层而在夜侧流出的净Birkeland电流的存在。从分析中还检测到半球间场向电流。(2)通过对中纬度地磁场资料的分析，发现了净Birkeland流系统的季节依赖性。(3)AE、ap和ASY指标之间的高度相关性被解释为当前系统影响的共同表现。极地高频雷达数据分析利用SuperDARN高频雷达网获得的数据研究了极地F区电离层不规则性。讨论了不规则性发生的统计分布及其机理。
