Electron precipitation in the midday auroral oval

Journal of Geophysical Research: Space Physics, 1981
Simultaneous observations of auroral displays and electron precipitations by the DMSP 33 satellite provide an excellent and unique opportunity to study precipitation characteristics of the midday auroral oval. Attention is given to two topics: (1) the nature of the ‘gap’ of the midday discrete auroras which is a permanent feature of the dayside auroral

Structure of Disturbed Magnetosphere and Auroral Oval

Physics of Atomic Nuclei, 2017
A brief description of the structure of the magnetosphere—that is, permanent and temporary radiation belts, plasmasphere, and plasma layers—is presented. It is shown that the results of measurements of properties of energetic particles and plasma are sufficient for such a description.

Birth and Life of Auroral Arcs Embedded in the Evening Auroral Oval

2011
We report on all-sky camera observations at Ft. Simpson during the crossing of the FAST spacecraft on 09 March 2008 at about 19:00 MLT. FAST registered eight auroral arcs with the associated upward currents and two periods of downward currents during the crossing time of five minutes. All arcs were moving equatorward with speeds near 300 m/s.
