The Sierra auroral sounding rocket provides three-point observations of ion distributions at the poleward edge of a pre-midnight auroral breakup arc system. Comparisons between the bulk flows calculated from the distribution at one point, and the motions of boundaries and structures as seen by relative delays between the three points, allow an examination of flows and motions under auroral arcs. Associated three-point DC electric field data provide another measurement for comparison. Positions and timing for each of the three measurement points are provided by onboard GPS measurements, providing high accuracy for the interpayload comparisons. We present a study of these motions, and relate them to the associated electron precipitation behavior, with examples from both Alfvenic and inverted-V type arcs.
