CME from Sun to hit Earth this weekend

Washington: The sun erupted with an Earth-directed coronal mass ejection, or CME, a solar phenomenon that can send billions of tons of particles into space and reach Earth on August 24 or 25, says NASA.

These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground.

According to NASA, CME left the sun at speeds of around 380 miles per second, which is a fairly common speed for CMEs.

Earth-directed CMEs can cause a space weather phenomenon called a geomagnetic storm, which occurs when they funnel energy into Earth’s magnetic envelope, the magnetosphere, for an extended period of time.

The CME’s magnetic fields peel back the outermost layers of Earth’s fields changing their very shape.

In the past, geomagnetic storms caused by CMEs of this strength have usually been mild.

Magnetic storms can degrade communication signals, cause unexpected electrical surges in power grids, and produce aurora at higher latitudes.
