Space Weather. Solar flares can lead to Coronal Mass Ejections (CMEs) from the sun which when they reach the earth a few days later can disturb the Earth's magnetic field. The plot shows estimates of the Kp index, which is a measure of this disturbance. A Kp of 5 or greater indicates a geomagnetic storm. If the disturbance is strong enough (probably 8 or 9 on the scale) then major power and communications disruptions can occur. For more see this quick guide.
