Who cares about GPS accuracy? :-)
By SETH BORENSTEIN, AP Science Writer Seth Borenstein, Ap Science Writer – Thu Apr 2, 5:20 pm ET WASHINGTON – 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 manmade global warming are marginally reduced, though just by three-tenths of a degree at most. http://news.yahoo.com/s/ap/20090402/ap_on_sc/sci_quiet_sun_2 -- Jim Reisert AD1C/Ø, <jjreis...@alum.mit.edu>, http://www.ad1c.us ----------------------------------------------------------- To unsubscribe or subscribe to this list.
