Ionospheric Event 2013-10-02


SUMMARY OF THE EVENT: A CME that left the sun at midnight on October 2nd generated a geomagnetic storm (Kp between 5 and 7) (source: As a consequence the Earth ionosphere was disturbed on October 2nd with an increase of TEC in the south and a decrease in the North. The next day (03/10/2013) the TEC decreased with respect to the median of the 15 previous days.

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).
