Fewer sunspots on sun

April 04, 2009|Times Staff and Wire Reports

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 human-caused global warming are marginally reduced, though just by three-tenths of a degree at most.

It's all a normal part of the strange but regular cycles of the sun's activity. Scientists don't know why it happens, but for humankind, they say, it's probably a good thing.
