Scientific paper

The NASA SIERRA rocket mission was a multiple-payload experiment which flew into a 100 nT auroral substorm at altitudes up to 735 km over the Poker Flat Research Range in Alaska on January 14, 2002. The SIERRA experiment was composed of electric field instruments, magnetometers, and particle detectors. Here we examine high resolution and high sensitivity electric field results from one of the three payloads. The particle instrumentation indicates an equatorward region of inverted-V electron precipitation followed by a poleward region of mostly field-aligned suprathermal electron bursts. In the inverted-V region, the electric field record reflects the precipitation in that it varies inversely with the intensity of the electron precipitation. In the poleward precipitation region, the average electric field is much larger, 50 mV/m compared to 20 mV/m, with time varying components that exceeded 100 mV/m and periods of 0.5-5 s. We interpret the electric field fluctuations, also observed in the magnetometer data, as Alfvenic, and we compare the Poynting vector of the fields with the electron precipitation fine structure.
