Source - Space Weather News for August 30, 2017:

GEOMAGNETIC STORM IN THE OFFING: A canyon-shaped hole has opened in the sun's atmosphere, and it is spewing a stream of high-speed solar wind toward Earth. NOAA forecasters say there is a 30% chance of polar geomagnetic storms (G1-class) when the gaseous material reaches our planet on August 31st. High-latitude sky watchers should be alert for auroras this Thursday and Friday.
