Current Problems of Magnetic Storm Prediction and Possible Ways of Their   Solving
  Main problems of magnetic storm prediction and causes of low efficiency of medium-term prognosis are discussed. It is supposed, that possible way of their solving is searching for poor-investigated features of solar wind (for instance, solar wind density behavior before storms). The necessity of investigation not only severe storms and coronal mass ejections (CMEs), but origin of moderate and weak storms is shown. Examples of successful investigations in this direction are given.
