The simulation results show that increased initial density before the onset of precipitation leads to smaller electron temperature increases, longer ionospheric heating

The table shows the following, in columns from left to right: The date of each event, whether or not UVI is available, the IMF B y at onset, the dipole tilt

We find that (1) the amplitude of high-frequency fluctuations in both R1 and R2 increases as the large-scale R1 and R2 FACs intensify; (2) high-frequency fluctuations in R1 peak

Following the above selection, the patch can easily be extracted as all pixels within the closed contour. Each contour is considered valid over the fluctuation. If we are not able

The phase scintillation follows the intense poleward edge of the aurora as it expands northward (across the patch) and reaches values

We want to compare how the speed of the nightside convection on closed field lines in the dawn and dusk convection cells varies for different IMF directions

The closed field lines on the dayside get twisted by the combination of erosion of flux at high-latitude flanks and by the increase of magnetic pressure in the northern dawn and

It is therefore necessary to model subauroral ionospheric convection during geomagnetically quiet conditions and to compare the results with longitudinally extended observations
