Earth-directed coronal mass ejection
What a surprise event we got yesterday! Sunspot region 2790 which decayed over the past few days and seemingly only has a simple magnetic layout, delivered with a long duration C7.4 solar flare. As mentioned in the news article yesterday, this solar flare was eruptive and it quickly became apparent that it launched a coronal mass ejection which is likely to hit Earth.
