Two rockets, SISSI (Spectroscopic Infrared Structure Signatures Investigation) F2 and F3, were launched during summer twilight conditions at ESRANGE, Kiruna, Sweden in July and August 1990. The payloads contained, in addition to other experiments, an infrared radiometer for the measurement of the OH Meinel (3-1) band and O2 (1(Delta) g) emissions and a resonance fluorescence experiment for the measurement of [O]. SISSI F2 was launched during a fading noctilucent cloud event and F3 during a solar proton event. For both rocket flights and for rocket ascent and rocket descent, an unexpected enhancement of the emission monitored by the OH radiometer was observed above 90 km. The glow was not detected by the O2 radiometer, was spin modulated, and was different in intensity for the two flights. Atomic oxygen concentration altitude profiles for F2 and F3 were different in peak concentration and in shape and exhibited a spin modulation that correlated with the glow spin modulation. We use these unique data sets with steady-state equations to model and investigate the odd-oxygen concentrations in the polar mesosphere during summer twilight conditions.
