ULF/ELF plasma waves in the active regions of the magnetosphere

The bow shock, magnetopause, plasma sheet and plasma sheet boundary layer are the regions in the plasma environment of the Earth, where intensive conversion of energy takes space. In present paper these regions are called the active regions. Low frequency plasma waves which can control the dynamics of the ions in collision free plasma play very important role in the formation and behaviour of these regions. This paper presents review of the observations of low frequency plasma waves (0.1 - 105 Hz), which were done by the PROGNOZ-8 satellite in the vicinity of the bow shock, at the dayside and nightside magnetopause within the flux transfer events and in the magnetotail. Common features of the studied regions are accelerated plasma streams, hot electron populations and very strong wave activity, particularly at the low frequencies. The detailed study of the wave spectra together with the distribution function for electrons indicate the correlation between presence of the lower-hybrid waves and the population of the particles with higher energy then in the surrounding space. The orbit of PROGNOZ-8 (apogee 32R(E) inclination 65 degrees) allows us to study regions where the ISEE-1, 2 and AMPTE satellites did not operate.
