Evolution of disturbance daily variations /DS/ and interplanetary plasma parameters
Abstract
The evolution of DS during the storms of Feb. 7 and Feb. 16, 1967 and Oct. 31, 1968 is studied. It is shown that DS usually evolves as a morning maximum and a dusk minimum but not necessarily simultaneously. Also, the maxima and minima may shift to other LT sectors too. DS continues to be high even in the recovery phase and generally ends up as a noon-time decrease. DS seems to be related with solar wind parameters N and V but not with interplanetary magnetic field.
