Investigators conduct further terrestrial nightglow observations to characterize the 500-1000 nm region, initially using long integration times and nightly co-adding spectra to maximize signal-to-noise ratio. The initial goal, obtaining a high-quality survey spectrum, is expanded with higher resolution measurements of isotopic bands in the b-X O-O band region. Accurately determined intensities of these bands (and other transitions), and their variability with vibrational level, provide important information on the energy flow among the oxygen electronic states, the ultimate source being the recombination of oxygen atoms. Simultaneous SRI experimental programs also stand to benefit some of these observational questions.

研究人员进行进一步的地球夜光观测，以表征500-1000 nm区域，最初使用长积分时间和夜间共添加光谱，以最大限度地提高信噪比。 最初的目标，获得高质量的调查光谱，扩大与更高分辨率的测量同位素带的b-X O-O带区域。 精确测定这些能带（和其他跃迁）的强度，以及它们随振动能级的变化，提供了关于氧电子态之间能量流动的重要信息，最终的来源是氧原子的复合。 同步SRI实验项目也有利于这些观察问题。
