A new database of the green-line corona brightness as compiled for the last five solar cycles and its possible utilization in the ISCS project

Abstract

Abstract Patrol coronagraphic measurements, regularly carried out by a small world-wide network of observatories, were synthesized to create a reliable and homogeneous set of the Fe XIV 530.3 nm coronal emission line intensity data. Our set of data enables to study different aspects of the solar activity, its variability and periodicity, especially in the large-scale and long-term scales. At the same time, the data on the green-line corona brightness and distribution of this brightness over the Sun's surface seem to be physically very relevant for a better understanding of the structure and some significant processes in the heliosphere. It is believed that an extensive analysis of our last five solar cycles database and its successive creation during the coming 23rd solar cycle could be a significant source of knowledge during the proposed “International Solar Cycle Studies” project.
