Calm solar cycle prompts questions about impact on Earth »
The surface of the sun has been surprisingly calm of late -- with fewer sunspots than anytime in in the last century -- prompting curious scientists to wonder just what it might mean here on Earth. But this cycle -- dubbed cycle 24 -- has surprised scientists with its sluggishness. "It is the weakest cycle the sun has been in for all the space age, for 50 years," National Oceanic and Atmospheric Association physicist Doug Biesecker told AFP. The intense electromagnetic energy from sunspots has a significant impact on the sun's ultraviolet and X-ray emissions as well as on solar storms. Source Main page (current trends)
