摘要

A brief review of results of observations of coronal mass ejections (CMEs), obtained aboard SOHO and STEREO during last decades, is presented. CMEs velocity, acceleration, mass and angular width arc considered in connection with the flares arising simultaneously with the CMEs from common solar regions. Statistically properties of associated CMEs-flares arc related. So, higher the flux of the associated flare is, higher the CME mass, angular width and velocity arc. The magnetic helicity of an active region (AR) seems to play an important role whether a confined or a CME-associated flare will be produced. The dynamical evolution of CMEs shows that the total energy is kept relatively constant and the energy released in radio and other forms of radiations is not significant. Slow CMEs could propagate through heliosphere with a deflection of 2 - 30° both in latitudinal and azimuthal direction obeying an interaction with the surrounding magnetic field. Faster CMEs tend to propagate radially. Data from published scientific papers and Internet have been used.
