Ionospheric Event 2013-03-01

Contact: iono@gnss.be

SUMMARY OF THE EVENT: The Total Electron Content (TEC) in the ionosphere was disturbed over Europe during the day of the 01/03/2013 between 9:15 and 14:30 UTC, and between 18:00 an 21:30 UTC. The peak of the disturbance was at noon and is characterized with an increase of the TEC over Europe of +17 TECu in average. These ionospheric disturbances can be corrolated with the increase of the geomagnetic index Kp (Kp=5 at Dourbes) (more information at www.sidc.be and www.swans.meteo.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).
