Ionospheric Event 2013-03-01


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 and ).
