An active region on the sun – an area of intense and complex magnetic fields – rotated into view in October. Labeled AR 12192, it soon grew into the largest such region in 24 years, and fired off 10 sizable solar flares as it traversed across the face of the sun. The region was so large it could be seen without a telescope for those looking at the sun with eclipse glasses, as many did during a partial eclipse.
