Research on Solar Flares and Solar Active Phenomena

本次合作研究(A)的目的是组织地面太阳光学和射电观测者的研究人员与x射线太阳物理卫星Yohkoh研究小组的研究人员一起，以最大限度地提高该领域的研究成果，因为Yohkoh卫星现在被世界研究人员视为该研究领域的前沿观测工具。重要的是要充分利用它的新观测结果。此外，我们打算在这方面促进更多的国际合作，因为有很多来自国外的数据要求。基于这一目的，本项目支持ISAS Yohkoh数据分析中心对来自其他来源的数据与Yohkoh数据进行合作分析，并帮助地面观测员与Yohkoh研究小组进行交流。我们在日本天文学会的会议上召开了联合会议…更多的是为了比较不同波长观测到的数据。我们在国内举办了“太阳和恒星上的超高温和高能现象研讨会”，以总结不同波长观测的研究人员之间的扩展联合研究，以寻求Yohkoh新发现现象的机制。最后，我们计划在结束为期三年的合作研究(A)时召开一次国际会议，请求国际天文学联合会的赞助，这是一个已经显示出显著产出的研究领域可以得到的。我们成功地得到了它，并于5月22日至26日在Makuhari举行了IAU第153次研讨会，“太阳大气中的磁动力现象——恒星磁活动的原型”。由于大多数日本研究人员的报告是基于他们与目前的合作研究(A)的研究，我们在这里附上了关于合作研究(A)成果的小册子的一堆手稿。少

The purpose of this Collaborative Research (A) is to organize the researchers of the ground-based optical and radio observers of the Sun together with the researchers in the research team for the X-ray solar physics satellite Yohkoh, in order to maximize the research outputs in this field, because the satellite Yohkoh is now regarded to be the cutting-edge observational tool by the researchers of the world in this research field, and it is important to make the most of the new observational results from it. Also, we intended to promote more of the international collaboration in this context because there are so many request of data from abroad. According to this purpose, the present project supported the cooerative analysis of data from other sources together with the Yohkoh data at the Yohkoh Data Analysis Center of ISAS,and helped the exchange between the ground-based observers and the Yohkoh research team. We held the joint meetings at the Meetings of the Astronomical Society of Jap … More an for the sake of comparison between the data observed in different wavelengths. We had a domestic symposium, "Symposium on Superhot and High Energy Phenomena on the Sun and Stars", in order to summarize the extended joint research between the researchers from different wavelength observations to seek for the mechanisms for the newly found phenomena by Yohkoh. Finally, we planned to hold an international conference in closing the thre year Cooperative Research (A), by asking for the sponsorship of the International Astronomical Union, which the field of research having shown conspicuous output can get. We successfully get it, and the Meeting was held as IAU Colloquium No.153, "Magnetodynamic Phenomena in the Solar Atmosphere---Prototypes of Stellar Magnetic Activity", on May 22-26 at Makuhari. Since the presentations by most of the Japanese researchers were based on their researches with the present Cooperative Research (A), we attach here the bunch of the manuscripts for the booklet on the outcome from the Cooperative Research (A).
