Like many of you, I stayed up as late as I could hoping to see aurora and then finally went to bed. The coronal mass ejection (CME) - that high-speed soup of electrons and protons shot from the sun by Wednesday's X5.4 flare - arrived around 6 a.m. this morning. The forecast calls for more northern lights through tonight as Earth's protective magnetic bubble called the magnetosphere continues to reverberate from the impact.
