AB: The four-satellite CLUSTER mission offers the opportunity to look at the time sequence and spatial pattern of electric field intensification at times near substorm onset. Using data from the Electron Drift Instrument (EDI), the Flux-Gate Magnetometer(FGM), and the Composition instrument ( CODIF), intense perpendicular flows ( ~40 km/s) towards the neutral sheet can often be seen around the time of onset, followed by expansion of the plasma sheet. Comparisons of these observations with MHD simulations of substorms will be presented.
