A systematic temporal correlation has been found between the energetic particle intensity variations measured at 6.6 RE and the development of large scale auroral features. The intensification and equatorward drift of east-west oriented stable discrete homogeneous auroral arc systems coincides with the decrease in energetic particle intensity at 6.6 RE as the nightside magnetosphere develops into a more tail-like configuration. The subsequent major breakup of the aurora coincides with the recovery in particle intensity as the field returns to a more dipolar configuration. Since this prominent decrease-increase sequence must be related to the intensification or inward convection of the tail current plasma sheet configuration followed by its diversion or dissipation, the auroral correlation documented here closely links the auroral particle precipitation to the plasma sheet and tail current dynamics.
