SUMMARY OF THE EVENT: The Total Electron Content (TEC) in the ionosphere was disturbed during the night of the 30/09/2012 to the 01/10/2012 at Europe's high latitutes. These disturbances might be linked with the CME impact which was detected by ACE the 30/09/2012 at 22:17 UTC (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).
