Two types of geomagnetic storms and relationship between Dst and AE indexes
E3S Web of Conferences, 2017 The study of the relationship between Dst and AE indices of the geomagnetic field and its manifestation in geomagnetic storms in the XXIII solar cycle was carried out. It is shown that geomagnetic storms are divided into two groups according to the ratio

A statistical study of the likelihood of a super geomagnetic storm occurring in a mild solar cycle
Earth and Planetary Physics, 2018 The activities of geomagnetic storms are generally controlled by solar activities. The current solar cycle (SC) 24 is found to be mild; compared to SCs 19–23, the storm occurrence and size derived by averaging the occurrence number and Dst around the ...

Observations of Ion Density and Temperature around the International Space Station During two Geomagnetic Storms [PDF]
, 2018 The International Space Station (ISS) is a low Earth orbit research facility and host to an international crew. Geomagnetic storms cause changes in the Earth’s magnetic field and affect the ion density and temperature in the ionosphere which could pose a

Statistical Relationship between Sawtooth Oscillations and Geomagnetic Storms [PDF]
Journal of Astronomy and Space Sciences, 2008 We have investigated a statistical relationship between sawtooth oscillations and geomagnetic storms during 2000-2004. First of all we selected a total of 154 geomagnetic storms based on the Dst index, and distinguished between different drivers such as ...

Geomagnetic storm dependence on the solar flare class
, 2006 Content. Solar flares are often used as precursors of geomagnetic storms. In particular, Howard and Tappin (2005) recently published in A&A a dependence between X-ray class of solar flares and Ap and Dst indexes of geomagnetic storms which contradicts to
