6 Fig.a presents the active distribution versus the solar wind velocity (IMP-8 measurements / 1 3 / ) • It: is evident that in the first half of the year active periods arise near the moments of velocity increasing. The connection between С and D se quences and the hi g h speed streams is clearly seen. The streams connecting w i t h A and В sequences have be e n formed after the beginning of the year, at first two ro tations the streams are not observed. In the second half of the year the number of streams reduces; during the first half of the Bartel's rotation the sharp increasings of the solar wind velocity is absent. It m a y be noted that the active period arises as a rule simulteneously with solar wind velocity increasing itself is not enough for increasing of activity. The data make an impression that active periods arise as a consequence of the collision of two corpuscular streams caused the crush of the magnetic field normally located in equatorial place. The waves producing IMP component appear; hi g h south wa r d B z produces the m a gnetоspheric substorm. During the first half of the ye a r an additional southward B^ is created by negative IMF component. In the Russian text the description of concrete disturbances of the year is given and their correspondence to the above mentioned statement is analysed. In the volume geomagnetic observations made by L.'i'.Afanasjeva,auroral observations - by L.S.Bvlashin,G.V.Starkov and G.F.Totunova are used. The analysis and description of activity description are made b y B.E.Brunelli. The volume is prepared to publication by L.V.Kovalevskaya.
