Blast from Sun Unsettles Earth’s Magnetic Field, but No Storming

January 13, 2014By
Image of the sun on Tuesday, Jan. 7, 2014, from the Solar X-Ray Imager on NOAA's GOES satellite, taken just after the maximum emission of a solar flare. The eruption came from the middle of the sun and is directed toward Earth. This is the largest solar flare so far this year.

Forecasters at NOAA’s Space Weather Prediction Center said the sun’s coronal mass ejection (CME) that reached Earth on Jan. 9, unsettled the geomagnetic field but did not cause storm conditions to be reached due to the weak magnetic field. While there is still a chance we could see some geomagnetic storming, that threat is greatly diminished. The Space Weather Prediction... read more
