AB: Recently, several studies have been devoted to the interaction of interplanetary shocks (IPS) with the Earth's magnetospheric boundaries - the bow shock and the magnetopause. Non-stationarity of interaction of these large structures requires multi-spacecraft observations with good space and temporal coverage. The first half-year after the Themis fleet launch offers rich multi- spacecraft observations of the bow shock and magnetopause structures and their reaction to the interplanetary shocks with very suitable space configuration. In the contribution we analyze selected interplanetary shocks observed by multiple spacecraft in the solar wind and their passage through the bow shock - magnetosheath - magnetopause structure. Themis multi-spacecraft measurements allow us to study the deformation of the IP shock and movement of the magnetospheric boundaries, estimate their orientation and speed and compare them with various theoretical and simulation models.
