Baku-APA. The Sun erupted with an Earth- directed coronal mass ejection, or CME, at 2:09 a.m. EST (0609 GMT) on Thursday morning, U.S. APA reports quoting Xinhua.

Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory, and Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 575 miles per second, which is a fairly typical speed for CMEs. Historically, CMEs at this speed are mild, NASA said in a statement.

A CME is a solar phenomenon that can send solar particles into space and reach Earth one to three days later.

Earth-directed CMEs can cause a space weather phenomenon called a geomagnetic storm, which occurs when they connect with the outside of the Earth's magnetic envelope, the magnetosphere, for an extended period of time. In the past, similar CMEs have caused auroras near the poles but didn't disrupt electrical systems on Earth or interfere with GPS or satellite-based communications systems.
