Extreme Geomagnetic Storms – 1868 – 2010

Solar Physics, 2016
We present the first large statistical study of extreme geomagnetic storms based on historical data from the time period 1868 - 2010. This article is the first of two companion papers. Here we describe how the storms were selected and focus on their near-Earth characteristics.

Randomness in Geomagnetic Storms

Fractals, 1997
Although geomagnetic forecasting is extremely important, geomagnetic predictions usually rely on forecasters' experience in distinguishing events expected to be geoeffective. Initial investigations with powerful forecasting techniques such as neural networks have recently been applied to geomagnetic prediction, but these are based on the assumption ...

Geomagnetic Index for Intense Ionospheric Storm

2019 Russian Open Conference on Radio Wave Propagation (RWP), 2019
© 2019 IEEE. From analysis of the geomagnetic activity indices aa and ap it is obtained that the index aa can be more adequate indicator of geomagnetic activity for the ionospheric parameters at periods of maxima of intense magnetic storms than ap. This is supported by analysis of the F2-layer critical frequency over Irkutsk station at the period of ...
