Drifting electron holes (DEH)
- last update: 7 January, 2115 UT (RR)
Drifting electron holes (DEHs), originally found in the geosynchronous particle data
(Sergeev et al., 1992) are substorm
related regions of decreased
energetic (tens and hundreds of keV) electron fluxes that drift around the Earth just like electron
injections (enhancements of fluxes) do. It has been shown that
DEHs actually are injections that just happen to result
to decrease of fluxes at the observed energies and radial
distances (Shukhtina et al., 1996).
