NASA warns of solar storm racing toward Earth this week

Computerworld - NASA issued a warning Tuesday that a coronal mass ejection may reach Earth this week, possibly affecting satellites and electronic systems on the ground.

On Tuesday, at 4:24 a.m. ET, the sun erupted with an Earth-directed coronal mass ejection, which is a huge burst of solar wind and magnetic fields shooting into space, NASA reported. This solar phenomenon can launch billions of tons of particles into space, reaching Earth one to three days later.

With that time frame, the particles could reach Earth between today and Friday.

The solar particles won't harm humans, but they can affect satellites and electronic systems, breaking up communication signals and causing electrical surges in power grids.

The space agency noted that the coronal mass ejection burst from the sun at speeds of about 570 miles per second.

Geomagnetic storms, or temporary disturbances in the Earth's magnetosphere, caused by coronal mass ejections are generally mild.

Early in 2012, the largest solar flare in six years caused problems for some GPS systems, airline communications systems and satellites for a few days.
