  • Balloon Image HAO's HiWind Launch

    HAO's HiWind, a balloon-borne instrument that measures winds in the thermosphere, was launched from Esrange, Sweden. It ascended about 26 miles (43 kilometers) into the atmosphere and headed west across the Atlantic Ocean, passing above Greenland on its way to Canada in round-the-clock sunlight. Read More »

  • HiWind Recovery HiWind's Recovery Mission

    HAO's HiWind data and payload was successfully recovered! HiWind is the first balloon-borne FPI to measure the daytime thermospheric winds that are critically needed for space weather research. The HiWind payload has modest pointing requirements combined with a modest weight. Read More »

  • K-Coronagraph PDRK-Coronagraph

    The K-Coronagraph successfully completed its PDR (Preliminary Design Review) and will now move forward towards completion of the instrument build in 2012 —starting full operations at Mauna Loa Solar Observatory in the Summer of 2013. See Photo »

  • Solar ActivitySlowdown in Solar Activity

    The Sun drives our climate, so a slowdown in solar activity would surely put the brakes on global warming—wouldn't it? That question percolated through the media at a recent solar physics meeting of the American Astronomical Society in Las Cruces, New Mexico.

Dr. Chihoko Yamashita (University of Colorado) has successfully defended her Ph.D. thesis, titled "Atmospheric Coupling Through Gravity Waves During Stratospheric Sudden Warming". Chihoko's research has been supported by the HAO Newkirk Graduate Student Fellowship for the last four years. She has been very productive and was the Second Place Winner (2009 and 2010) and First Place Winner (2011) in CEDAR Student Poster Competitions. Her work was also highlighted in the July 2011 issue (page 19) of SPARC (Stratospheric Processes And Their Role In Climate) Newsletter. See Chihoko Yamashita's 2010 Profile in Science— Read More »
