Long-duration Solar Flare

Source - Space Weather News for Sept. 9, 2014: http://spaceweather.com

This morning (Sept. 9th at 00:30 UT) the magnetic canopy of sunspot AR2158 erupted, producing a long-duration solar flare and a bright CME.  The CME, which billowed away from the sun at nearly 1,000 km/s,  has an Earth-directed component.  A glancing blow is possible during the late hours of Sept. 11/early hours of Sept. 12.  High-latitude sky watchers should be alert for auroras when the storm cloud arrives.
