J. Raeder (2006) presented the results of a global magnetohydrodynamic simulation indicating that flux transfer events (FTEs) form solely in the winter hemisphere and move poleward in the direction of the background magnetosheath flow during periods of strongly southward interplanetary magnetic field (IMF) orientation. This paper presents results from a statistical survey of flux transfer FTEs observed on the mid‐latitude northern and southern magnetopause by the magnetometer on the Interball‐1 spacecraft over the course of its five‐year mission from 1995 to 1999. Interball‐1 observations confirm that FTEs exhibit a strong tendency to occur in the winter hemisphere.
