Space radiation enhancement linked to geomagnetic disturbances.

Optimal Transmission Line Switching under Geomagnetic Disturbances

In recent years, there have been increasing concerns about how geomagnetic disturbances (GMDs) impact electrical power systems. Geomagnetically-induced currents (GICs) can saturate transformers, induce hot spot heating and increase reactive power losses. These effects can potentially cause catastrophic damage to transformers and severely impact the ability of a power system to deliver power. To...

Effects of geomagnetic disturbances on humans functional state in space flight

Investigations of the effect of geomagnetic activity influence on the heart rhythm regulation of cosmonauts during the expeditions onboard the Soyuz spacecraft, and the MIR orbital space stations was carried out for various durations of flight in weightlessness and, under control of groups of cosmonauts who were inspected under flight conditions outside the geomagnetic disturbances and in groun...

Disturbances in the US electric grid associated with geomagnetic activity

Large solar explosions are responsible for space weather that can impact technological infrastructure on and around Earth. Here, we apply a retrospective cohort exposure analysis to quantify the impacts of geomagnetic activity on the US electric power grid for the period from 1992 through 2010. We find, with more than 3r significance, that approximately 4% of the disturbances in the US power gr...

Which Environmental Factor Is Correlated with Long-Term Multiple Sclerosis Incidence Trends: Ultraviolet B Radiation or Geomagnetic Disturbances?

Background Insufficient received ultraviolet B radiation (UV) is regarded as the main environmental risk factor (RF) for MS in vitamin D deficiency hypothesis. Nevertheless, geomagnetic disturbance (GMD) has also been proposed as a potential trigger for MS in GMD hypothesis. The aim of this study was to investigate which of these mentioned RF is correlated with long-term ultradecadal MS inciden...
