The number of black Sunspots on the surface of the Sun indicate the Sun's activity level (image credit: NASA).

Based on counts of sun spots on the surface of the Sun, it looks like our star is heading towards a solar minimum. This happens every 11 years or so, and is related to how the internal and external magnetic fields in the Sun interact with each other. Keeping track of this activity is important, because it can help us predict geomagnetic storms on Earth.
