SOLAR WIND SPARKS GEOMAGNETIC STORM: Earth is entering a stream of high-speed solar wind flowing from a hole in the sun's atmosphere. First contact with the stream on Sept. 14th produced a moderately strong (G2-class) geomagnetic storm, ongoing at the time of this alert. If the storm continues, high-latitude sky watchers could see auroras after local nightfall on Sept. 14/15.
