The polar-orbiting Ogo 6 UV photometer was designed to measure the high-altitude airglow in the zenith at heights between 400 and 1100 km. However, at low latitudes and below 800 km the short-wavelength channel (sensitive to Lyman alpha 1216 ¿) showed localized increases in apparent intensity above the normal Lyman alpha airglow signal. Their large intensities (up to 8 kR) and their high altitude of occurrence make it unlikely that the instrument was recording UV emission. The morphology of the occurrence of these mainly quiet time events points to the possibility of direct charged particle interference. This interference is not caused by trapped inner Van Allen belt particles. It appears that the responsible particles are quasi-trapped soft (<1 MeV) protons which are confined to low latitudes and low altitudes, at least during those local times for which they have been observed. Such a soft proton belt was discovered in 1972 by Moritz; however, no information on the geographical or local time dependence was known. The Ogo 6 observations have a distinct and unusual morphology, which may reflect the geographical and local time behavior of the protons, as well as their pitch angle distribution.
