Airglow continuum dependence in the 8700 Å bandpass on solar activity parameters, and on the OH and O₂ line emissions. High solar activity coincides with slow solar wind in our dataset. Observation N^o 6 from January 2, 2022, with the highest measured 8700 Å radiance, is a potential outlier, as discussed in Sect. 5.4, and is indicated with a hollow symbol. The OH flux is a sum of blended 7-3 R OH lines (~8761, 8768, 8778, and 8791 Å in our spectra), while the O₂ flux is a sum of blended O₂ P and Q-branch lines in the range 8645–8696 Å.
