Our planet will undergo a bombardment of electromagnetic particles that should affect our technologies ...
Attention storm. From Thursday, the largest solar flare in five years will lead to Earth particle bombardment electromagnetic might disrupt satellite communications and electrical distribution networks, announced Wednesday the U.S. authorities.
This eruption of solar plasma occurred Tuesday night and its effects should not be felt on our planet before Thursday morning around 13h French time, to last until Friday, according to forecasts by the National Oceanic and Atmospheric (NOAA).
Increase in solar flares
This solar storm, charged particles that hit the Earth at a rate of 6.44 million km / h, can potentially affect the distribution of electricity, satellite communications, GPS, astronauts on the International Space Station (ISS) and compel airlines to change their routes to avoid the polar regions.
A spokesman for NASA told AFP that the agency took no specific action because "we do not believe that the ISS crew is in danger." "Increasing the number of solar flares - the last occurred on January 23 - is normal in terms of business cycles of eleven years the sun, which for this period is expected to peak in 2013, " NASA explained.
One of the most powerful since 2006
Such intensification of solar flares is more common as the sun completes one cycle of activity minimum to start a much longer active. The solar storm is probably "one of the most powerful since December 2006," according to Joseph Kunches, space weather expert at NOAA.
Besides the risk of disrupting communications satellites now highly dependent, the latter probably solar storm will create auroras in Central Asia on Thursday evening, promises Joseph Kunches. These experts point out that the Earth is well protected from these solar storms by its magnetic field.
