What might happen to the well-known 11-year solar cycle if the Sun were spun up to rotate more than two times faster? To investigate such questions of the dependence of the Sun's internal dynamo on parameters such as rotation we must look to other stars with different physical conditions.

In a recent AGU editor's Vox Discussion, Delores Knipp explores the societal impacts of geomagnetically induced currents (GICs). GICs can cause voltage swings, transformer heating, and reactive power loss in high-voltage power transmission systems.

Modeling a grand minimum image
Monday, November 9, 2015

Recently, scientists at NCAR's High Altitude Observatory—using a 3-D computer model—may have uncovered an important clue. Their model, which they hoped would simply mimic the Sun's mysterious 11-year solar cycle, spontaneously plunged into its own grand minimum.
