• Description:
  Research of the temporal variations of solar ultraviolet radiation is reviewed. Progress on a collaborative program to analyze Dr. D. F. Heath1s NIMBUS-7 SBUV measurements of the solar UV spectral irradiance is summarized. Significant progress has been made on determining the wavelength and temporal characteristics of UV variations caused by solar active region evolution (birth, growth, peak, decay and occasionally rejuvenation) and by solar rotation (area foreshortening, center-to-limb darkening and limb occultation). Work on trying to corroborate an observed semiannual UV variation has commenced. Extensive progress on modeling solar UV variations has been achieved. Support for improved rocket-flight measurements of solar UV spectral irradiance is discussed. The importance of obtaining accurate recalibration is stressed. Recalibration flights are needed to permit accurate intercomparison of the NIMBUS-7 solar UV measurements at the maximum of solar cycle 21 with the SBUV/2 measurements planned for the upcoming solar minimum and for solar cycle 22.
