Solar flares are directed to Earth

The cloud of charged particles could affect today and satellite navigation and electric power. The largest solar storm in five years is about to shake the Earth's magnetic field.

After going through the day and a half space, a huge cloud of charged particles arrive today and could affect electricity networks, satellite navigation systems and flight of aircraft, especially in regions of the northern hemisphere.

However, the same storm may produce colorful auroras at the poles further away than usual.Scientists said on Wednesday that the storm, which began with a huge solar flare earlier this week, is growing as it moves away from the Sun, rising like a huge soap bubble.

When you come to Earth early today, the particles will move more than six million miles per hour. "We are hitting right on the nose," said Joe Kunches, a scientist at the National Oceanic and Atmospheric Administration (NOAA for its acronym in English), based in Boulder, Colorado.

Astronomers say the Sun has been relatively quiet for a while and this storm, though strong, may appear fiercer because the Earth has been lulled for several years by a weak solar activity.

The storm is part of the normal cycle of 11 years the Sun, which is supposed to reach a peak next year storms.
