Yesterday, Sept. 14th, an eruption near sunspot 1289 hurled a CME in the general direction of Earth. Analysts at the Goddard Space Weather Lab expect the cloud to deliver a glancing blow to our planet's magnetic field on Sept 17th around 04:30 UT. There are no large coronal holes on the Earth-facing side of the sun. High-latitude magnetic storms are possible when the CME arrives. (SpaceWeather)

A near M-Class solar flare reaching C9.2 took place at 20:51 UTC Wednesday around new Sunspot 1297 which formed in the southern hemisphere. Keep an eye on this fast growing region for further activity.
While watching the latest LASCO2 movie you can see a faint but full halo Coronal Mass Ejection (CME) blasting away from the sun and a portion of it may impact earth. It appears that a majority of the material will sail wide. This took place during the early hours Wednesday morning.
Solar activity has been fairly low since the C9.9 Solar Flare around Sunspot 1296 on Monday. There will remain a chance for an M-Class flare around the region of 1295-1296.
A new sunspot that should be numbered 1297 is quickly forming in the southern hemisphere between regions 1287 and 1290. These spots will rotate onto the western limb by the weekend. (SolarHam)
Geophysical Activity Summary 13/2100Z to 14/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.
Geophysical Activity Forecast:
The geomagnetic field is expected to be at predominantly quiet levels for the period (15-17 September). The CME is expected to be geoeffective.
Alerts / Bulletins
Latest Alert: Sep 15 0505 UTC CONTINUED ALERT: Electron 2MeV Integral Flux exceeded 1000pfu
Last Advisory Bulletin: None in last 7 days.
Solar activity continues at moderate levels. The target region NOAA 11295, which has produced two low C-class flares since the last message, has been classified as a beta region and may be the decaying plage of NOAA 11271 from the previous rotation. Further isolated C-class events possible.
The position of NOAA 11295Â on 14-Sep-2011 at 15:30 UT is: N21E49, ( -677", 267" ) (SolarMonitor)
