AB: We present a series of Cluster (at ~19 Re) and Polar (at ~9 Re) magnetotail alignments when large activity was observed in the plasma sheet on at least one of the two locations. We present the energy flux available in Alfven waves and examine the dissipation of that energy in the region between Cluster and Polar. We comment on the implications of our findings for the inward evolution of the flows and for plasma heating.
