The ultraviolet spectrometer-telescope on Copernicus was used for stellar occultation measurements of atmospheric ozone. Two sets of observations of the target star Beta-Cen were carried out on 26 July 1975 and 13-14 June 1976 at wavelengths from 255

Detection of two new soft X-ray sources and their identification with the supernova remnants (RNRs) 3C400.2 and MSH 15-56, is reported. From the observed X-ray flux in the 0.7–2.0 keV energy range, the X-ray luminosity of 3C400.2 is derived to be i

Data gathered on solar gamma-ray events by the gamma-ray spectrometer on board the HEAO-3 satellite are discussed. Measurements were made of both hard X-ray and gamma-ray events. A total of 37 flare-like incidences were detected from October 1979 to
