All of these sunspots are stable

All these sunspots have stable magnetic fields that pose little threat for strong solar flares.
Satellites are often lost during extreme geomagnetic storms. The reason: Models of Earth's upper atmosphere break down during some storms, introducing errors in estimates of satellite drag. A new study published in Space Weather solves the problem using a clever trick. Instead of modeling the atmosphere, researchers from MIT analyzed decades of satellite orbits to learn how spacecraft respond to space weather. When a storm hits, those historical patterns reveal what satellites are likely to do next. (Spaceweather.com).
