Ionospheric Event 2013-10-14

Contact: iono@gnss.be

SUMMARY OF THE EVENT: The ionosphere was disturbed the 14th and 15th of October 2013, characterized by an increase of TEC the 14th and followed by a depletion of TEC during the 15th. These disturbances are linked with the geomagnetic activity index Kp which was in the active range (4-5) (see swans.meteo.be), probably due to the M1.7 solar flare of the 13th of October 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).
