AB: We have conducted analysis of particle data from the lower-altitude Polar and higher-altitude Cluster spacecraft, when they were in magnetic conjunction on field lines that intercepted the dayside cusp and cusp boundary layer. From this analysis we obtain a better understanding of the accelerated, injected plasma and the nature, source, and extent of electric fields associated with inverted-Vs observed in this region. For the years 2001 and 2002 we have identified 4 or 5 such examples. One goal of the analysis is to determine the nature and extent of the electric field between the spacecraft and determine its possible relationship to dayside reconnection sites.
