It is widely accepted that magnetic disturbances around fast interplanetary magnetic clouds can play an important role in their geo-effectiveness. An analytical solution for magnetic field in the sheath region of a cylindrical magnetic cloud with an elliptical cross-section is proposed. Upstream magnetic field can have an arbitrary direction. Normal magnetic field components are conserved through the bow shock with a high accuracy.
