Shrinking Atmospheric Layer Linked to Low Levels of Solar Radiation
Thu, Aug 26th, 2010
Large changes in the sun's energy output may drive unexpectedly dramatic fluctuations in Earth's outer atmosphere.
Results of a study published today link a recent, temporary shrinking of a high atmospheric layer with a sharp drop in the sun's ultraviolet radiation levels.
The research, led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., and the University of Colorado at Boulder (CU), indicates that the sun's magnetic cycle, which produces differing numbers of sunspots over an approximately 11-year cycle, may vary more than previously thought.

CAPE CANAVERAL AIR FORCE STATION, Fla. (AFNS) -- A team from the 45th Space Wing successfully launched the first Advanced Extremely High Frequency satellite onboard an Atlas V launch vehicle from Launch Pad 41 here Aug. 16 at 7:07 a.m.
"This is an historic launch of an important asset to our nation's military and our allies," said Undersecretary of the Air Force Erin C. Conaton. "The AEHF satellite will provide secure, protected communications capability across the spectrum of mission areas, including land, sea and air warfare. Its benefits will be felt in special operations, strategic nuclear deterrence, strategic defense, theater missile defense and space operations and intelligence.
