The PIs will measure the excess brightness of the Sun in the CaII K-line, bringing up to date the sequence of measurements obtained at McMath-Hulbert from 1944-1979, and at Big Bear from 1979-1987. The CaII index is an important measure of the level of solar activity, solar ultraviolet emission, and excess solar constant emission. As such, it plays a basic role in the SunRISE program. The measurements in this project will separately evaluate the emission from highly active regions, normal plages, and the chromospheric network, all of which are known to be associated with sources of ultraviolet emission.***

PI 将测量 CaII K 线中太阳的多余亮度，从而更新 1944 年至 1979 年在 McMath-Hulbert 以及 1979 年至 1987 年在 Big Bear 获得的测量序列。 CaII指数是衡量太阳活动、太阳紫外线发射和过量太阳恒定发射水平的重要指标。 因此，它在 SunRISE 计划中发挥着基础作用。 该项目中的测量将分别评估高度活跃区域、正常区域和色球网络的发射，所有这些都已知与紫外线发射源相关。***
