This paper presents the results of observation of ionospheric response to severe magnetic storm on September 25, 1998 (Ap = 121). Storm caused the significant changes in the ionosphere behavior: the increase of the height of the electron density peak hmF2, the large fall of the peak electron density NmF2, increase of plasma temperature and significant infringement of plasma exchange processes between low and upper ionosphere.
