Solar Storm Warning: Sun Shoots Major X1,6 Flare Outburst at Earth

Major Solar Flare
Geoeffective Sunspot 2158 produced a strong solar flare this afternoon measuring X1.6 at 17:45 UTC. The event event was associated with a Type II Radio emission with an estimated velocity of 3750 km/s. This is indicative of a strong coronal mass ejection. Updated imagery by SDO shows plasma racing away from the blast site and  towards Earth. More updates once coronagraph imagery is available. http://www.solarham.net/

X-FLARE: Earth-orbiting satellites have just detected a powerful X1.6-class solar flare (Sept. 10 @ 17:46 UT). The source was active sunspot AR2158, which is directly facing Earth. NASA’s Solar Dynamics Observatory recorded the extreme ultraviolet flash.  http://http://spaceweather.com/

2014-09-11 05:01 UTC  A Pair of CMEs  New  Update 

G2 (Moderate) geomagnetic storms remain in the forecast for September 12th as a result of the coronal mass ejection (CME) associated with the R1 (Minor) solar flare observed on the 9th. The latest WSA-Enlil model run has the CME associated with yesterday’s R3 (Strong) solar flare arriving mid to late day on that same day. A G3 (Strong) Geomagnetic Storm Watch has been issued for September 13th due to the combined influence of these two events with G1 (Minor) storming anticipated to continue into September 14th. In addition, the S1 (Minor) solar radiation storm that is in progress as a result of the eruption yesterday is expected to persist for the next few days. Keep in mind that the forecast periods listed are in Universal Time so aurora watchers in the northern U.S. should be looking for possible activity both Thursday and Friday nights. Stay tuned for updates.
