- The YOHKOH satellite, also called "Sunbeam" was launched into space from the Kagoshima Space Center (KSC) in Southern Japan. This is a project of the Japanese Institute of Space and Astronautical Science (ISAS). The scientific objective has been to observe the energetic phenomena taking place on the Sun, specifically solar flares in x-ray and gamma-ray emissions. Instruments on the satellite: the Bragg Crystal Spectrometer (BCS) the Wide Band Spectrometer (WBS) the Soft X-Ray Telescope (SXT) the Hard X-Ray Telescope (HXT) Additional information available at "http://hesperia.gsfc.nasa.gov/sftheory/yohkoh.htm"
