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

In the bot- tom panel of Figure 11, which shows the time pro fi le of the Dst index, the colors of the vertical lines indicate the L-shells of EMIC wave activity during the

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

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

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
