Long-duration solar flare Yesterday 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. Check http://spaceweather.com for m
