Pilipenko DETERMINATION OF THE LATITUDE PROFILE FOR THE RESONANCE FREQUENCY OF THE Pc5 PULSATIONS BY EISCAT RADAR DATA In this paper, we consider the long-period geomagnetic Pc5 pulsations in the morning se c to r for the event of 29 April 2001 ob served at stations of IMAGE profile and at the Barensburg (BAB) station. The manifestations of the re son an c e properties were ob se rved for geomagne tic Pc5 pulsations: the d e c re a s e of frequency of Pc5 pulsations with increase of the geomagnetic latitude, ch ang e of the ph a se and ellipticity during p a s s a g e through the re so n an c e region. For the study of the g eom agnetic Pc5 pulsations manifestation in ionosphere parameters, the d a ta of the incoherent sc a tte r VHF EISCAT radar in Tromso were used. The b e am of the VHF EISCAT radar w a s inclined on 30° to the horizon and directed to the Spitsbergen. So, the increase of height along the radar b e am w a s a ccompan ied by the increase of the geom agn e tic latitude. The clear Pc5 pulsations were ob served in the line of sight velocity of the ionospheric p lasma from 68 to 72 d e g re e s of g eom agnetic latitude that correspond to the height of 100-410 km. At the s am e time, the clear Pc5 pulsations were not observed in the density, ion and electron temperatu re of the ionosphere plasma. The spectral analysis show s the d e c r e a s e of frequency of Pc5 pulsations in ionosphere p lasma velocity with the increase of the g eom agnetic latitude. This fact indicates about manifestation of the re so n an c e properties in the ionosphere plasma velocity. So, the possibility w a s shown to determ ine the latitude distribution of the re son an c e frequency of Pc5 pulsations from the radar d ata obtained in a fixed point. Keywords: solar-terrestrial physics, ionosphere, magnetosphere, geomagnetic pulsations, arctic latitudes, incoherent scatter radar. Authors Vladimir B.
