At the beginning of the 1990s, it was found out that the strongest disturbances of space weather were associated with huge ejections of matter from the solar corona, which took the form of the magnetic clouds when moved from the Sun. It is the collisions of the magnetic clouds with the Earth's magnetosphere that lead to strong, sometimes to catastrophic, changes in space weather. The onset of a coronal mass ejection (CME) is sudden and no reliable forerunners of CMEs have been found till now. The problem of CME prediction is less developed than the problem of solar flare prediction. The most probable initial magnetic configuration of a CME is a flux rope consisting of twisted field lines which fill the whole volume of a dark coronal cavity. Cold dense prominence material can be collected in the lower parts of the helical flux tubes. Filaments are then the best tracers of the flux ropes in the corona, visible long before the beginning of the eruption. [ABSTRACT FROM AUTHOR] |
