Why so much solar activity? Sun may be outpacing predictions.

It’s no coincidence that the headlines have been full of solar flares and storms: Solar cycle 25, as astronomers call it, is now well under way.

Solar activity, which space weather experts measure by the number of visible sunspots, rises and falls on a cycle that lasts roughly 11 years from minimum to minimum, although one cycle can be as short as nine years or as long as 13. The sun‘s new cycle is about two years in and should peak around 2025; although cycle 25 is expected to be stronger than its predecessor, it is still predicted to be feebler than average.
