Signs in the Sun

Grab eclipse glasses: Large sunspots visible, produce solar flares - UPI.com
UPI reports: "We're heading into the bottom of solar minimum, when the sun tends to have fewer sunspots, solar flares and coronal mass ejections - large expulsions of plasma, electrons and ions and magnetic fields. But despite where we are in the sun's cycle, activity on the sun has dramatically picked up over the past few days. On and off, these two sunspots have been flaring and shooting out coronal mass ejections, directed toward Earth. [...] We don't need to worry about this coronal mass ejection being 'the big one' - a solar storm direct hit that could cause widespread power blackouts and trigger as much as $2 trillion worth of damage, according to a National Academy of Sciences study. But this storm, on the back of this month's abnormally active space weather, may wind up on the larger end of the scale, and will be the subject of lots of analysis and research."
