Strongest solar storm since 2005

Washington - Space weather officials say the strongest solar storm in more than six years is bombarding Earth with radiation, with more to come.
The radiation is mostly an issue for satellite disruptions and astronauts in space. It can cause communication problems for polar-travelling aircraft.
The Space Weather Prediction Centre in Colorado observed the flare Sunday at 04:00. Physicist Doug Biesecker says the biggest concern is the radiation, which arrived on Earth an hour later. It will probably continue through Wednesday.
Biesecker said the storm's radiation levels are considered strong but other storms have been more severe. It is the strongest level since May 2005.
Plasma ejected from the sun arrives on Tuesday, but is not as strong. It can extend the visibility of auroras and disrupt the electrical grid.
