The multi-payload sounding rocket SIERRA was successfully launched on 1/14/02 from Poker Flat, Alaska into active post-breakup aurora. The three GPS-equipped payloads carried electric and magnetic field probes, as well as several different particle detectors. The main payload carried a new instrument to measure the thermal core of the electron population. These particles may carry currents between the topside ionosphere and the magnetosphere and its drifts may trigger wave instabilities. Initial analysis results from this new instrument will be presented. Primary emphasis will be placed on interpreting the instrument response, and differentiating between the effects of secondary particles and the thermal core. Also, we will compare the thermal electron behavior with more energetic ions and electrons and will place the measurements in the context of previous theoretical results, including models of auroral energy deposition and Alfvenic acceleration.
