Аннотация:Results of the investigations of low latitude boundary layer (LLBL) properties are presented. Data, obtained on high apogee satellites, are used. Intervals of multi satellite observations are selected when one satellite was inside the magnetosheath and the other crossed magnetopause and measured plasma parameters in LLBL. Amplitudes of magnetic field fluctuations in the magnetosheath are compared with the values of magnetic field inside the magnetosphere. Such values are determined for case studies using observations inside the magnetosphere and results of model calculations. It is shown, that amplitudes of magnetosheath magnetic field fluctuations are comparable with the values of magnetic field inside the magnetosphere in the near cusp regions. The role of magnetosheath turbulence in LLBL formation is discussed.
