The intenstiy of solar radiation in 10-¿ intervals in the wavelength region 1230--1940 ¿ is presented, based on measurements with a rocket spectrometer flown twice, on November 2, 1973; and again on April 23, 1974. The estimated errors in the fluxes are ¿20%. The fluxes are compared with measurements of others and are shown to be in good agreement with those of Parkinson and Reeves reported in 1969. The present data are used to compute the O2 photodissociation coefficient as a function of the O2 column density.
