AB: We survey the occurrence of reconnection jets at the poleward edge of the cusp detected by Cluster as a function of the interplanetary magnetic field (IMF) clock angle. The survey covers 3 years (2001-2003) of data and is restricted to periods of relatively stable IMF. Our survey indicates that these jets occur only when the IMF clock angle is within ~50 degrees of the GSM z direction. We will discuss this finding in relation to component versus anti-parallel merging models.
