The Solar-A ('Yohkoh') satellite was launched in August 1991. This satellite aims at studying the sun in X-ray. So far the satellite performs quite satisfactorily, returning spectroscopic and imaging data of the solar corona and the solar flares. An important knowledge which Yohkoh has brought to us is that the solar corona is more dynamic and magnetically structured than we anticipated, and full understanding of the coronal physics inevitably requires the observations of the chromosphere and the photosphere with the best available resolution.The project we proposed aims at combining high quality optical data obtained at the observing facilities in both countries together with X-ray data from Yohkoh. For this purpose the Japanese participants visited Kiepenheuer Institute and discussed scientific programs to be pursued under this cooperative program. As an outcome of this cooperation, the first coordinated observation was carried out in the period of 3-13 August, 1993. Observatories around the world including those in Japan and in the Canary islands (Spain) participated in this campaign. Several interesting research topics were identified and analyzed in a workshop held in 1994 February. Initial results of this campaign will be presented at the spring meeting of the Astronomical Society of Japan.

Solar-A （'Yohkoh'）卫星在1991年8月发射。这颗卫星旨在用x射线研究太阳。到目前为止，这颗卫星的表现相当令人满意，它传回了太阳日冕和太阳耀斑的光谱和成像数据。Yohkoh带给我们的一个重要知识是，太阳日冕比我们预期的更具动态性和磁性结构，全面了解日冕物理不可避免地需要以最佳分辨率对色球层和光球层进行观测。我们提出的项目旨在将两国观测设施获得的高质量光学数据与Yohkoh的x射线数据结合起来。为此目的，日本与会者访问了基彭豪尔研究所，并讨论了在该合作计划下要进行的科学项目。作为这种合作的结果，在1993年8月3日至13日期间进行了第一次协调观察。世界各地的天文台，包括日本和加那利群岛（西班牙）的天文台都参加了这项运动。1994年2月举行的一次讲习班确定和分析了几个有趣的研究题目。这项运动的初步结果将在日本天文学会的春季会议上公布。
