Solar Storm Forecasts Improve as Sun’s Fury Increases
Space.com- If this week's raging solar storm was any indication, the sun is ramping up its activity — and scientists will be ready for it. By meticulously studying our planet's star, they are able to predict these potentially dangerous space weather events better than ever before.
A huge solar flare erupted Jan. 23, triggering the strongest radiation storm in nearly a decade. A wave of charged particles, called a coronal mass ejection (CME), bombarded Earth yesterday (Jan. 24). The bombardment is over now, but some minor disruptions to spacecraft and power grids were reported.
Scientists' forecast for the arrival of the disruptive wave was off by only 13 minutes, far more accurate than in the past. And with much of the world's networks interconnected and populations increasingly reliant on technology, the ability to predict and track potentially harmful space weather events will become ever more crucial.

Solar flares and CMEs are expected to increase in frequency as the sun emerges from the dormant phase of its 11-year activity cycle.
