The event is probably the strongest in nearly six years, said Joseph Kunches, a specialist in U.S. space weatherWASHINGTON, March 7. – A geomagnetic storm is moving from the Sun to the Earth, and its arrival is scheduled for Thursday which could affect power grids, roads and aircraft navigation systems, space satellite, U.S. experts said.The storm, a cloud of charged particles ejected from the Sun to about 7.2 million miles per hour, had its origin in a pair of solar flares, scientists said.
This is probably the strongest event in nearly six years, and is probably more intense than a similar storm occurred in late January, said Joseph Kunches, a space weather specialist of the National Oceanic and Atmospheric Administration (NOAA .)
In the view of the solar disturbance Kunches this is a matter of three stages and the first two are already affecting the Earth:
Firstly, two solar flares that were traveling near the speed of light reached Earth on Tuesday night. These flares can cause radio blackouts.
Subsequently, solar radiation reach the Earth’s magnetic field on Wednesday, causing a potential impact on air traffic, especially near the poles, satellites and any astronaut who perform spacewalks. This phase can last several days.
Finally, it is expected that the plasma cloud sent by the coronal mass ejection, which is basically a large part of the Sun’s atmosphere, comes to Earth early Thursday.
This phase can affect power grids, satellites, pipelines and high-precision GPS systems, used by oil drillers, surveyors and some agricultural operations, scientists said.
