This proposed research, a precursor to the SunRISE Program, plans to reduce and analyze Mt. Wilson Observatory CaK spectroheliograms obtained on a daily basis between 1915-1988. These images provide by far the longest reliable record of solar photospheric faculae and chromospheric plages. The plan is to analyze the behavior of these structures in active regions and in the network over the past seven solar cycles, for information on the sun's magnetic fields and activity levels that is complimentary to data obtained from the sunspot index, and from other much shorter data bases such as solar magnetograms. The obtained results should assist upper atmospheric physicists and climatologists in ongoing efforts to improve prediction and dynamical understanding of solar activity cycles.

这项拟议中的研究是日出计划的前身，计划减少和分析Mt。威尔逊天文台在1915-1988年期间每天获得的CaK太阳光谱图。这些图像提供了迄今为止最长的太阳光球光斑和色球斑的可靠记录。该计划将分析这些结构在过去七个太阳活动周期中在活跃区域和网络中的行为，以获得有关太阳磁场和活动水平的信息，这些信息与从太阳黑子指数和其他更短的数据库（如太阳磁图）获得的数据互补。所获得的结果应有助于高层大气物理学家和气候学家正在进行的努力，以提高预测和动态的太阳活动周期的理解。
