Abstract
The flare activity and especially the proton-flare activity is concentrated in the zones of ‘Bartels' active longitudes’ and in the neighbourhood closest to the sector boundaries of the interplanetary magnetic field. This concentration seems to be greater if the importance of the event increases.
