M6.9 coronal mass ejection, G1 geomagnetic storm watch
SOHO/LASCO coronagraph imagery is now available to analyse the coronal mass ejection that was launched during the M6.9 solar flare from yesterday. Good news: this coronal mass ejection indeed has an earth-directed component. A minor G1 geomagnetic storm watch is in effect for 21 and 22 December.
