The Sun has been going through a quiet spell recently, with fewer sunspots than in almost one hundred years. This can have benefits to satellites, GPS and other systems while even global warming is reduced, albeit by a very small amount.
The sun has been unusually quiet lately, with fewer sunspots and weaker magnetic fields than in nearly a century. A quiet sun is good for Earth: GPS systems are more accurate, satellites stay in orbit longer; even the effects of man-made global warming are marginally reduced, though just by three-tenths of a degree at most."
