... Observations of precipitating (Jp) and trapped (Jt) energetic (> 30 keV) particle fluxes at the ionospheric altitudes within the auroral oval region has revealed the existence of a sharp boundary separating the poleward zone of isotropic precipitation (Jp = Jt) from the equatorward zone of weak loss cone filling (Jp << Jt) at all local times (Sergeev and Malkov, 1988). ... boundaries for higher energy particles are located at lower latitudes than boundaries for lower energy particles . ...

... The eboxdetect task has two different modes of operation: (1) local detection and (2) map detection. eboxdetect is first run in local mode. The local mode source lists serves as input for task esplinemap which creates background maps (one per energy band for each EPIC instrument) which are then used to run eboxdetect in map mode. ... In both modes, source searching is only performed in the area of the images which is marked by an optional detection mask created by task emask . ...

Cosmic ray intensities (left) compared with predictions (right) from IBEX. The similarity between these observations and predictions as evidenced by the similar color regions supports the local galactic magnetic field direction determined from IBEX observations made from particles at vastly lower energies than the cosmic ray observations shown here. The blue area represents regions of lower fluxes of cosmic rays. ...

... Because of the low conductivity, the magnetic coupling is weak and depends critically on density, temperature, ionisation rate and charged species. ... Implications When the Hall regime dominates near the midplane and ambipolar diffusion is dominant closer to the surface, a thicker layer of the disc is unstable to MRI perturbations and modes grow faster than under the ambipolar diffusion approximation. ... Right panel: For weak coupling, Hall limit perturbations grow until vA/cs ~ 2.9. ...
