So how likely are
such magnetic storms?»
Not exact matches
Space weather events
such as geomagnetic
storms can disturb Earth's
magnetic field, interfering with electric power grids, radio communication, GPS systems, satellite operations, oil and gas drilling and air travel.
Past observations of
such unusual auroras can therefore allow us to determine the frequency and severity of
magnetic storms.
Now, a new study suggests that one
such «coronal mass ejection» in 2015 temporarily weakened Earth's protective
magnetic field, allowing solar plasma and radiation from the same
storm to more easily reach the atmosphere, potentially posing a danger to astronauts.
Blake concludes, «We can now monitor and model
magnetic storms in near - real time, which not only allows us to understand the physics of
such phenomena, but also to provide a valuable service for power operators.»
