UPDATE!!

Filament Eruption Near 1608

A filament eruption was just observed over the last several hours around sunspot 1608. This region is in a good Earth facing position and a Coronal Mass Ejection (CME) is now visible. A portion of the cloud looks to be Earth directed. More updates to follow.

 

The brand new CME Prediction Model released by the Goddard Space Flight Center shows a potential for an Earth impact by late on November 12. A majority of the slow moving plasma cloud appears to be headed south, however a glancing blow impact will be possible. This could lead to an increase in geomagnetic activity and aurora at high latitudes.

 

FARSIDE EXPLOSION: As solar activity picks up on the Earthside of the sun (see "Broken Quiet" below), the farside of the sun is coming alive, too. During the early hours of Nov. 9th, a magnetic filament located behind the sun's southeastern limb erupted, hurling a bright coronal mass ejection (CME) into space:

This explosion was not geoeffective, but future explosions might be. The blast site, still potent, is just days away from rotating onto the Earthside of the sun

 

 

ALERT: Type II Radio Emission

Begin Time: 2012 Nov 08 0220 UTC

Estimated Velocity: 784 km/s

Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.

 

Solar activity remains at very low levels. The largest visible sunspot this morning, is a new region forming in the northwest quadrant. There is currently no chance for strong solar flares.

 

New sunspots are active
