C Class Solar Flare & CME

[Thomas F. Giella]

Posted Saturday December 13 2008 at http://www.kn4lf.com/kn4lf72.htm :
On Friday December 12, 2008 fleeting sunspot group #11009 produced a C class solar flare before setting around the west limb of the Sun. This is the first C class solar flare since April 03, 2008. 

Also a filament eruption occurred in the northwest quadrant of the Sun beginning at approximately 0615 UTC. This produced a weak partially geo-effective (Earth facing) coronal mass ejection (CME) that "may" impact Earth's geomagnetic field in a minor way (Kp 3) on or about Monday December 15, 2008.
