What did scientists spot days before the solar flare?

The third most-powerful solar flare ever observed in X-ray wavelengths erupted from Sunspot 486 early October 28, 2003, at approximately 6 a.m. Eastern Standard Time. A coronal mass ejection (CME) directed almost straight at Earth preceded the flare, sending electrically charged gas toward our planet, say NASA and European Space Agency (ESA) scientists. To follow up, the same spot released a large X11 flare Wednesday afternoon and it too is associated with a CME.
