Since 1962 the Space Research Division of the Royal Observatory Edinburgh have been planning and launching a number of rocket experiments aimed at observing the absolute stellar fluxes of early-type stars in the region 1000 Å–3000 Å. Although some earlier attempts were unsuccessful due to rocket failures, good photometric data have been obtained from four successful flights in 1967 and 1968, and it is the purpose of this short report to indicate the nature of the data rather than give a complete scientific analysis.
