Ionospheric Event 2016-01-20


SUMMARY OF THE EVENT: Following the CME of the 18th January, minor to moderate geomagnetic storms disturbed the ionosphere on the 20th of January. The Total Electron Content was increased with a maximum of 10 TECu during the sunshine hours above Europe and was unstable during the night until early morning of the 21st of January.

Figure 1 shows the time evolution of the Vertical Total Electron Content (VTEC) (in red) extracted from the near-real time VTEC maps at 3 different latitudes (Figure 2): a) Northern part (top), b) Brussels (middle) and c) Southern part (bottom). Also shown, the model based on the median from the 15 previous days (in grey).
