The sun is more active than experts predicted. It could mean more grounded flights, downed satellites, and stunning aurora.
Briefly

The heightened solar magnetic activity that's been growing is now so strong it chokes energy from deep inside the sun, causing cooler pockets on the surface.
We didn't think the sun was going to be as active this particular cycle, but the observations are completely opposite, indicating unexpected solar behavior.
Tracking sunspots is crucial because they are ground zero for powerful X-class solar flares and massive eruptions that can disrupt Earth's technologies.
Recent data shows that 299 sunspots appeared within a day, marking the highest daily sunspot record in over 22 years.
