In order to provide basic information on the nature of the horizontal branch star, whose light dominates in the ultraviolet, observations of field horizontal branch stars as well as individual stars In globular clusters are discussed. Finally the IIJE observations of globular clusters in the Magellanic Clouds are exgmlned.

Seven blue horizontal branch stars in the field have been observed, and a few HB stars have been isolated in globular clusters. Energy distributions are compared to assess possible differences, also in comparison with model atmospheres. Observed energy distributions of HB stars in NGC 6397 are used
