"The strongest geomagnetic storm in more than six years is set to hit Earth's magnetic field on Tuesday and it could affect airline routes and power grids.
A large chunk of the Sun's atmosphere was hurled towards Earth on Sunday driving energized solar particles at about 5 million miles an hour.
According to meteorologists, this energy can interfere with high frequency radio communications used by airlines to navigate close to the North Pole in flights between North America, Europe and Asia.
Astronauts on board the International Space Station may be advised to shield themselves in specific parts of the spacecraft to avoid a heightened dose of solar radiation, the meteorologist from the center said.
The space weather center said the geomagnetic storm's intensity would probably be moderate or strong, levels two and three on a five-level scale, five being the most extreme."
