An X1.7 flare (largest category) and a coronal mass ejection (CME) erupted from the Sun (Jan. 27-28, 2012) from the same active region that produced a smaller but Earth-directed storm a few days earlier. This resulting solar storm was not squarely Earth-directed, but the clouds of high-energy protons that it emitted continued to hit the SOHO spacecraft detectors for over a day and did generate a minor radiation storm on Earth. (SOHO is about a million miles towards the Sun from Earth.) The CME raced away from the Sun at a fast at 2500 km/s or 5.6 million mph clip.

  • The title. There's a typo. I was like "X 17?!?!?! Already???"

  • Good job it wasn't a direct hit but I bet the aurora would have been phenomenal.
