Ionospheric Event 2013-10-09

Contact: iono@gnss.be

SUMMARY OF THE EVENT: The ionosphere was disturbed in the northern part of Europe during the night of the 8th of October. During the day of the 9th of October, a strong increase of TEC occurred in the southern part until 10:00 AM before depletion, whereas in the northern part only a decrease of TEC w.r.t. the median of the 15 previous days was observed. These ionospheric disturbances are most probably associated with the halo CME observed on the sun on the 6th of October (source: 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).
