Intermittency is one of the main features of the solar wind
turbulence. We investigate the intermittency of ion flux and magnetic field scalar fluctuations under large statistics of the high time resolution measurements onboard Interball‐1 spacecraft. A large degree of intermittency is observed in the solar wind, and it grows significantly from a large (more than 10000 s) to a small (less than 100 s) scales. We give a special attention to a comparison of intermittency for the solar wind observation intervals containing SCIF (Sudden Changes of Ion Flux) to ones for intervals without SCIF. Such a comparison allows us to reveal the fundamental turbulent properties of the solar wind regions in which SCIF is observed more frequently. Especially it is important that the intermittency of the high frequency (up to 1 Hz) plasma variations is investigated for the first time. So we significantly extend the range of intermittency observations for solar wind plasma.
