An emission feature at 1,026-{angstrom} observed at 600 km in the dayglow with a spectrometer on board the STP 78-1 spacecraft cannot be explained by geocoronal hydrogen Lyman {beta}. An accidental resonance of some lines of the O I multiplet at 1,026-{angstrom} with the broad solar Lyman {beta} line can in fact account for the observed emission rate, based on analysis with a Monte Carlo radiative transport model. Photoelectron excitation of atomic oxygen is negligible compared with resonant scattering. The airglow results support a ratio of 66 to 1 for the solar Lyman {alpha} to Lyman {beta} line center fluxes.
