M2.0/M2.6 CME analysis, weak CME impact
SOHO imagery is complete and that means it is time to analyse the coronal mass ejection from this morning's double peaked M2.0/M2.6 solar flare. For more information regarding these solar flares please read this news article.
M2.0 and M2.6 solar flares with full halo CME
A double peaked long duration solar flare (M2.0 and M2.6) took place around sunspot region 2371 early this morning between 01:42 UTC and 02:35 UTC. The beginning of a symmetrical (!) full halo coronal mass ejection is becoming visible on SOHO coronagraph imagery meaning an impact at Earth can be expected in a few days.
