Ultraviolet background radiation.
Abstract
The results are reported of observations in narrow bands centered on 1115, 1425, and 1446 A of the flux from an empty high-galactic-latitude region and from several stars. The observations had been obtained with the aid of three ultraviolet-sensitive Geiger counters which were carried on an Aerobee-150 rocket launched from the White Sands missile range on Mar. 13, 1969. The results obtained provide a basis for setting an upper limit to the flux from the Coma cluster of galaxies.
