High Time Resolution Auroral Electron Measurements
Abstract
The Ground-to-Rocket Electrons Electrodynamics Correlative Experiment (GREECE) sounding rocket was launched into active aurora on 03 March 2014, yielding a wealth of high time resolution precipitating electron measurements. One of several features observed was a dispersive signature early in the flight, on the up-leg, that appears to be associated with electrons accelerated by Alfven waves. This is well before apogee. In order to explore the aurora corresponding to these signatures we must use the oblique observations resolvable in the all-sky imagers deployed at Venetie, AK (apogee site) and Poker Flat, AK (start of the up-leg). The in-situ electric and magnetic field measurements will be examined as well.
