Abstract
Observations (1600–2950 Å) from the S3–4 satellite of the Earth's nightglow at ≈6 Å resolution have been analyzed. These data indicate that the only significant emissions from NO are the δ and γ bands. The relative brightness of these bands was consistent with previous observations at lower resolution. The data support the presence of O 2 emissions in the Herzberg I, II, and III bands in ratios (≈4.5:1:1.4), consistent with analyses of previous ground-based observations of these band systems. Spacecraft glow is seen from the N 2 Lyman-Birge-Hopfield bands, as previously reported; however, no spacecraft-related emissions were seen from NO or O 2.
