Abstract

Simple models of flare-generated magnetic clouds are considered in the light of magnetic measurements on board Vega 1 and Vega 2 during the solar-interplanetary events in January–February 1986. The models are in approximate accordance with the experimental data if the following conditions are satisfied: (1)the clouds are force-free finite aspect ratio toroids; (2) the large radius of each cloud is parallel to the magnetic axis of the nearest bipolar group; (3) the magnetic buoyancy, gravity, and hydrodynamical deceleration are taken into consideration.
