WebAbove Earth’s surface the magnetic field threads its way through the ionosphere, the electrically conducting part of the upper atmosphere where solar radiation maintains partial ionization. The degree of ionization is a function of altitude, latitude, time of day, season, and solar-cycle phase. That region is therefore called ionospheric dynamo region. [1] The magnetic manifestation of these electric currents on the ground can be observed during magnetospheric quiet conditions. They are called Sq-variations (S=solar; q=quiet) and L-variations (L=lunar) of the geomagnetic field.

WebResearchers have been puzzled by regular blackouts in the GPS navigation system on the European Swarm satellites where DTU Space leads the international scientific cooperation. The loss of signals occurs in particular when the satellites pass the equator between Africa and South-America. The reason is wild space weather.
