Abstract
WE have observed the far ultraviolet spectrum of β Lyrae using the Princeton spectrometer, on the Copernicus satellite1. The principal data were scans in the low resolution mode (0.2 Å in the (U2) region 1,000–1,500 Å and 0.4 Å in the (V2) region 2,000–2,900 Å) at phases nearly coincident with the two light minima. Shorter scans (1,100–1,300 Å) were obtained at the two quadrature phases. All observations were made in August and September 1973 but not in the same orbital cycle.
