Space Weather News for Feb. 14, 2018 http://spaceweather.com https://www.facebook.com/spaceweatherdotcom SUNSPOT EXPLODES, HURLS CME AT EARTH: On Feb. 12th, the magnetic canopy of sunspot AR2699 exploded--for more than 6 hours. The slow-motion blast produced a C1-class solar flare and hurled a coronal mass ejection (CME) almost directly toward Earth. NOAA forecasters say there is a 60% chance of minor G1-class geomagnetic storms with isolated periods of stronger G2 storming when the CME ...Continue Reading
