Forecasting space-weather effects on Earth
...possible effects on people and systems. The scales describe the environmental disturbances for three event types: geomagnetic storms, solar radiation storms and radio blackouts (not shown here). To convey severity they have numbered levels, analogous...

NOAA launches Crowdsourcing competition for better forecasting of magnetic field
... changes in Earth’s magnetic field. The transfer of energy from solar wind into Earth’s magnetic field causes geomagnetic storms. The resulting variations in the magnetic field increase errors in magnetic navigation. Over the past three decades...

Solar superstorms and their effects on Earth
...a magnetic orientation opposite that of Earth’s magnetic field transfers its energy most efficiently, thus producing a stronger geomagnetic storm. Aurora observations and sunspot drawings together provide a unique look into the past of the Sun Bright...

The next ‘unthinkable’ – global disruption from a solar storm
... can be generated. Three main types of space weather events are typically recognised: radio blackouts, solar radiation storms and geomagnetic storms. Radio blackouts occur when a strong burst of x-rays from a solar flare hits the Earth’s atmosphere...

Our view of Van Allen belts set to be revolutionised by new data from NASA probes
... for lower-energy electrons — up to 0.8 MeV — to fill this space during almost all geomagnetic storms and not just during the most extreme geomagnetic storms that happen about once every 10 years, as previously thought. The higher-resolution data...

SpaceX Starlink satellites fall out of sky after storm
... manoeuvres, and up to 40 of the satellites will reenter or already have reentered the Earth’s atmosphere, added SpaceX. Geomagnetic storms are the result of interactions between solar wind - a stream of charged particles from the sun - and Earth...
