ELECTION DAY SUNSPOT: One of the biggest sunspots in years is emerging on the sun today. Hours ago it produced a C-class solar flare and a minor radio blackout over the Indian Ocean. This sunspot, if it holds itself together, will face Earth for the next two weeks as it rotates across the face of the sun, potentially setting the stage for a sustained stretch of solar activity.
