Last year, we launched the solar-A satellite (now called 'Yohkoh'). This satellite aims at studying the sun in X-rays. So far the satellite performs quite satisfactorily, returning spectroscopic and imaging deta of the solar corona and the solar flares. An important knowledge whichYokoh has brought to us is that the aslar 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 Institut and discussed scientific programs to be pursued under this cooperative program. As an outcome of this cooperation, the first coordinated observation is scheduled in August, 1993.

去年，我们发射了太阳能-A卫星（现在称为“Yohkoh”）。这颗卫星旨在研究太阳的X射线。到目前为止，该卫星的表现相当令人满意，返回了日冕和太阳耀斑的光谱和成像数据。横滨带给我们的一个重要知识是，日冕的动态和磁结构比我们预期的更强，要充分了解日冕物理学，就必须以最佳分辨率观测色球层和光球层。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横滨的X射线数据结合起来。为此，日本与会者参观了基彭霍伊研究所并讨论了该合作计划下将开展的科学项目。作为这种合作的结果，第一次协调观察定于1993年8月进行。
