Аннотация: 
The study results of the F region and topside ionosphere response to moderate magnetic storm on 4‒6 April 2006 are presented. The observations were carried out with the Kharkov incoherent scatter radar. The magnetic storm was accompanied by the ionosphere storm with sign-variable phases. The feature of the ionosphere storm is presence of two positive phases of disturbance. The basic mechanisms forming development of positive and negative phases of the storm are considered.
