A Hole in the Sun's Atmosphere Turns Toward Earth

Source - Space Weather News for June 14, 2017:

A HOLE IN THE SUN'S ATMOSPHERE: Spewing a stream of solar wind as fast as 700 km/s (1.6 million mph), a hole in the sun's atmosphere is turning toward Earth. Forecasters expect the stream to reach our planet on June 15th or 16th with a 40% chance of minor G1-class geomagnetic storms when it arrives.  High-latitude sky watchers should be alert for auroras in the nights ahead, especially in the southern hemisphere where deepening autumn darkness favors visibility.
