An observation of O+ 834 Å nightglow emission

Abstract
A 40 Å resolution spectrometer was employed to measure the extreme ultraviolet nightglow emissions. The spectrometer was flown on a Black Brant V‐C rocket, which was launched at 21:08 MST on February 9, 1973, from White Sands Missile Range, New Mexico. The O+ 834 Å emission can be identified in the spectrum and has a brightness of 15±5 R. This emission is probably excited by the conjugate electrons. The data also indicate the presence of some nightglow emission in 950 to 1050 Å region that is still unidentified.
