Description

The impulsive behaviour of the green emission line corona brightness over the years is emphasized and illustrated by means of butterfly diagrams constructed for the last five solar cycles. This peculiar property of the solar coronal activity is supposed to be reflected by the heliospheric medium, as well. Evidence of coincidences of the coronal impulsive periods with the maximum values in the solar modulation of galactic cosmic rays is presented.
