An anomalous change of the spectrum of signals scattered by the ionospheric plasma was observed with the incoherent scatter radar of the Institute of Ionosphere during the strong geomagnetic storm on 30 May 2003. The change was observed for 1.5 h at heights from 700 to 1200 km. Such phenomenon was detected with the use of Kharkiv incoherent scatter radar for the first time. The results of the observations are presented and a procedure for determination of the disturbed ionosphere is described.
