Electron Density Variations during Ultraviolet Transient Events

High-resolution temporal observations performed with the SUMER spectrometer on SoHO provide an opportunity to investigate the electron density variations in thèquiet Sun' solar transition region due to UV transient events. Two datasets obtained in the density sensitive lines belonging to the O iv 1400 A multiplet were searched for such events, leading to the identiication of two explosive event...

Proton-electron precipitation eects on the electron production and density above EISCAT (Tromsù) and ESR

The suprathermal particles, electrons and protons, coming from the Sun and precipitating into the high-latitude atmosphere are an energy source for the Earth's ionosphere. They interact with the ambient thermal gas through inelastic and elastic collisions. Most of the physical quantities perturbed by the precipitation, such as the electron production rate, may be evaluated by solving the statio...

Enhancement of thermospheric mass density by soft electron precipitation

[1] Enhancements in F-region electron density and temperature and bottomside Pedersen conductivity caused by soft electron precipitation are shown to enhance the Joule heating per unit mass and the mass density of the thermosphere at F-region altitudes. The results are derived from the coupled magnetosphere-ionosphere-thermosphere model (CMIT) including two types of causally specified soft elec...
