X-FLARE: Active sunspot AR2158 erupted on Sept. 10th, producing a strong X1.6-class solar flare. Because the sunspot is directly facing Earth, this is a geoeffective event. HF radio blackouts and other communications disturbances have already been observed on the day-lit side of Earth. Stay tuned to http://spaceweather.com for more information and updates about the possibility of an Earth-directed CME and geomagnetic storms in the days ahead.
DON’T MISS THE STORM: Aurora alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
