Space Weather News for Dec. 17, 2017 http://spaceweather.com https://www.facebook.com/spaceweatherdotcom GEOMAGNETIC STORM IN PROGRESS: A G1-class geomagnetic storm is underway on Dec. 17th as Earth moves into a stream of solar wind. The gaseous material is flowing faster than 600 km/s from a hole in the sun's atmosphere. G1-class storms are relatively minor and have little effect on power grids and satellites. However, they can confuse migratory animals that navigate using magnetism at high l ...Continue Reading
