Ride the Roller Coaster to Solar Minimum:

Most of us live on a 24-hour cycle beginning with waking up, going about our jobs or other activities and then sleeping before waking up again. We call it the circadian rhythm from the Latin circa dia or “about a day.” The sun has a rhythm too, called the 11-year solar cycle. During that time, we see a rise in magnetic activity on the sun including sunspots (giant knots of concentrated solar magnetism); titanic solar storms called flares; and blasts of plasma — clouds of electrons and protons — billowing from our star. The hubbub peaks and then gradually declines. Sunspot numbers plummet as do the intensity and frequency of solar flares and phenomena like the aurora borealis which is tied to solar activity.
