The resonant fluorescent scattering of solar radiation in the vacuum ultraviolet by the Fourth Positive Band System of Carbon Monoxide is a process that contributes to the dayglow of planets whose atmospheres contain significant amounts of the gas. The scattering process should also be observed in comet tails and with any gaseous release above the atmosphere containing carbon monoxide such as a rocket exhaust. The author has carried out an accurate computation of single scattering intensities as a function of temperature and column density of CO and has also generated computer spectra using known oscillator strengths and transition probabilities. It is shown that the 14,0 band scatters the solar Lyman alpha line, and an estimate of this scattering intensity is made.
