Ionospheric Event 2013-03-17

Contact: iono@gnss.be

SUMMARY OF THE EVENT: The ionosphere was disturbed over Europe the 17/03/2013 with an abnormal increase of Total Electron Content (TEC) followed by a decrease the 18/03/2013. These ionospheric disturbances were due to the Solar Coronal Mass Ejection (CME) of the 15/03/2013, altering the geomagnetic activity to its storm level (k=5) on the 17/03/2013 (more information at: www.sidc.be).

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).
