(Newsroom America) -- NASA says the sun unleashed a coronal mass ejection (CME)at 11:24 p.m. EDT on Oct. 4. but it is not expected to cause any problems on Earth.
Not to be confused with a solar flare, which is a burst of light and radiation, CMEs are a phenomenon that can send solar particles into space and can reach Earth one to three days later.
Experimental NASA research models show the CME to be traveling at about 400 miles per second.
When Earth-directed, CMEs can affect electronic systems in satellites and on Earth.
"CMEs of this speed, however, have not generally caused major effects in the past," said NASA.
