A filament eruption (see video) near earth-facing sunspot region 2345 was associated with yesterday's strongest solar flare: C9.2 at 18:18 UTC. A Type II radio sweep was associated with this event and a faint asymmetrical full halo coronal mass ejection was launched towards Earth and could impact Earth this weekend.
