Journal ArticleDOI
A rocket measurement of the extreme ultraviolet dayglow
TL;DR: In this paper, the extreme ultraviolet spectra of the mid-latitude dayglow in the wavelength range of 550 to 1250A have been obtained with a rocket borne grating spectrometer at a resolution of 20A.
Journal ArticleDOI
Spectroscopy of the extreme ultraviolet dayglow during active solar conditions
TL;DR: The spectral characteristics of the mid-latitude daytime airglow observed between 530 and 1500 A under conditions of high solar activity are compared with those obtained at the same location during markedly lower solar activity as discussed by the authors.

TL;DR: In this article, the TIMED/GUVI dayglow observations are used to derive a new quantity, QEUVGUVI, which is a measure of integrated solar EUV electromagnetic energy shortward of 45 nm.
Journal ArticleDOI
High‐resolution auroral observations of the OI(7774) and OI(8446) multiplets
TL;DR: In this paper, high resolution observations of the OI(7774) and OI (8446) multiplet auroral emissions were made using a Fabry-Perot spectrometer at Churchill, Canada during March, 1984.
Journal ArticleDOI
The ultraviolet dayglow at solar maximum 1. Far UV spectroscopy at 3.5 Å resolution
TL;DR: The earth's far ultraviolet dayglow (1080-1515 A) was observed at about 3.5 A resolution during a period of high solar activity near solar maximum om June 27, 1980 as mentioned in this paper.
