SUMMARY OF THE EVENT: A CME hit the Earth magnetic field at 18:00 UTC the 24th of May 2013 (source: www.sidc.be). As a consequence, the Total Electron Content (TEC) of the ionosphere over Europe decreased until the 26th of May 2013.

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).
