Ultra-Fast Measurements of Precipitating Electrons in Earth's Cusp
Abstract
We present electron measurements from the Acute Precipitating Electron Spectrometer (APES). APES was flown on the VISIONS-2 sounding rocket which launched into cusp aurora on 07 December 2018. APES measured the precipitating electron distribution from 130 eV to 16 keV with 1 ms time resolution. The electron precipitation contained many features that exhibited energy-time dispersion, some of which extended up to greater than 10 keV, while others were as as short as 50 ms in time. The characteristics of these energy dispersed features will be quantified and discussed in the context of possible generation mechanisms as well as their implications for MI coupling.
