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将测量太阳在CaII K线上的多余亮度，更新1944-1979年在McMath-Hulbert和1979-1987年在Big Bear获得的测量序列。 CaII指数是衡量太阳活动水平、太阳紫外线辐射和过量太阳常数辐射的重要指标。 因此，它在日出计划中发挥着基础作用。 本项目中的测量将分别评价高活动区、正常谱区和色球网络的发射，所有这些都已知与紫外线发射源有关。
