Changes of equivalent widths for ten selected spectral lines (530.74 nm ≤ λ ≤ 568.82 nm) were evaluated according to "Belgrade Program for Monitoring of Activity-Sensitive Spectral Lines of the Sun as a Star". Observations from August 1987 till May 1990 have been processed in the way for the first time presented here.
