A statistical survey of the magnetotail current sheet

Using Cluster magnetometer data during summer 2001 and 2002, when the spacecraft traversed the magnetotail, we have performed a survey of current sheet and its current. We applied a superposed epoch analysis to simple, monotonous current sheet crossings and obtained a statistical profile of the current sheet. We find that the averaged structure of the current sheet fits well with the Harris current sheet description. By using the four spacecraft measurements, the current is calculated and a statistical current density profile of the current sheet is produced.
