> The solar flare emanated from the sunspot group AR3842, which has made headlines before. On Oct. 1, the same sunspot region fired off a powerful X7.1 solar flare and unleashed a coronal mass ejection (CME) — a plume of plasma and magnetic field — which is currently barreling toward Earth. That incoming CME is expected to hit Earth between Oct. 3 and Oct. 5, possibly triggering widespread auroras. I actually just saw an aurora for the first time in my life a few months ago in Oregon, where they're hardly ever visible. It was quite a sight. Maybe I'll get to see them again. |
