Several recent proposals to image sunlit magnetospheric O+ have been difficult to assess because of the lack of detailed knowledge of the solar spectrum at 834 ¿. An NRL solar spectrograph flown on a sounding rocket in 1962 actually had sufficient resolving power to allow the calculation of scattering rates. Using these solar data, examples of scattering rates for a range of thermal and bulk velocities are presented for both O+ and O++, and the effects of ionospheric albedo are estimated. The scattering rates are significantly lower than previously estimated for hot or moving plasma and exhibit substantial structure.
