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
Sorting the data according to the location of the sunlight terminator and orientation of the interplanetary magnetic field (IMF), we find that the equivalent current resembles
It is therefore necessary to model subauroral ionospheric convection during geomagnetically quiet conditions and to compare the results with longitudinally extended observations
Figure 2 shows a 20 ms window with reference time 25 October 2012 13:27:13.221 UT. The RHESSI counts are shown as blue dots with a logarithmic energy scale on the y axis. The
The simulation results show that increased initial density before the onset of precipitation leads to smaller electron temperature increases, longer ionospheric heating
From the direct comparison presented in Figure 7 we conclude that the westward ionospheric convection on closed field lines close to the nightside convection throat region in the
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
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
