GEOMAGNETIC STORM: A minor G1-class geomagnetic storm is in progress on April 11th as Earth moves through a high speed stream of solar wind. This is causing bright auroras around the poles, with Northern Lights sighted as far south as the Dakotas in the USA. The gaseous material is flowing from a wide hole in the sun's atmosphere--so wide that the stream could continue to influence our planet for the next two to three days.
