Ionospheric Event 2013-10-30


SUMMARY OF THE EVENT: Ionosphere was disturbed mostly in the northern part with an increase of TEC the 30th of October and a depletion the 31st. The origin of these disturbances are not well established. Despite that several flares (3X flares, see occurred from the 25th to the 28th, the geomagnetic activity (Kp index) remained at quiet and moderate level during these ionospheric disturbances.
