The absolute intensity and the centre-to-limb variations of the sun in the vacuum ultraviolet region were observed by the K-10-6 rocket flown from Uchinoura, Japan, on September 1, 1971, 1110 JST. The nose cone of the rocket was controlled to point the direction of the sun by a jet system within about ±20'. A trichrometer was used for the measurements, and the measured wavelengths were 1,629 A, 1,684 A, and 1,739 A. The spatial and spectral resolutions were 1'.3 and 8.3 A respectively. The obseaved results were compared with some solar models, and our results seem to fit best to the HSRA (Harvard Smithsonian Reference Atmosphere).
