In the paper we present a statistical study of so-called fast plasma flow (FPF) events, which periodically occurs along a wide distance range in the Earth's magnetotail, especially when the spacecraft crosses the central plasmasheet and plasmasheet boundary layer regions. Between November 2003 and January 2004 the Wind spacecraft voyaged behind MINUS SIGN 200 RE to the L2 point and recorded far magnetotail dynamics, including such kind of events, as a response to the solar wind activity.
The goal of this study is to detect and to separate the FPF events from over magnetotail dynamics data, to obtain their main parameters (velocity, plasma beta, magnetic field magnitude, etc.). Also, we try to explain evolution of probability of their observation along the WIND spacecraft orbit.
