AB: All magnetopause field lines concentrate in the cusp and the particles moving along these lines are bringing information on magnetopause processes wherever they occur. On the other hand, last results of Interball, Polar and Cluster missions have shown that the cusp itself and/or its vicinity is the crucial region for solar wind - magnetosphere coupling and that the principal processes are going on there. In the contribution, we would like to present the high-altitude cusp as a very busy and dynamic region that forms the whole magnetosphere and to stress out the role of IMF direction in the cusp formation. The considerations are based on statistics of the cusp identifications as well as on the analysis of dispersion patterns and plasma flows observed by the Interball-1/Magion-4 satellite pair.
