GEOMAGNETIC STORM PREDICTED: NOAA forecasters say there is a 45% chance of minor G1-class geomagnetic storms on Nov. 3rd when a stream of solar wind is expected to hit Earth’s magnetic field. The gaseous material is flowing from a large hole in the sun’s atmosphere. During G1-class storms, auroras can descend as far south as a line from Maine to Washington in the USA. Free: Aurora Alerts.
