SWIR air glow mapping of the night sky
Proceedings of SPIE, 2010It is well known that luminance from photo-chemical reactions of hydroxyl ions in the upper atmosphere (~85 km altitude) produces a significant amount of night time radiation in the short wave infra-red (SWIR) band of wave length 0.9 to 1.7 μm. Numerous studies of these phenomena have demonstrated that the irradiance shows significant temporal and ...

City Sky Glow Monitoring at Kitt Peak
Publications of the Astronomical Society of the Pacific, 1973A. A. HOAG, W .E.SCHOEMNG,ANI)M.COUCKE Kitt Peak National Observatoryt Photographs of night sky have been taken from Kitt Peak on clear moonless nights to provide a record of changes in contamination from artificial lights. Quantitative measures confirm the obvious qualitative impression that city sky-glow brightuess is increasing as is the case at ...

Measuring Anthropogenic Sky Glow Using a Natural Sky Brightness Model
Publications of the Astronomical Society of the Pacific, 2013Anthropogenic sky glow (a result of light pollution) combines with the natural background brightness of the night sky when viewed by an observer on the earth's surface. In order to measure the anthropogenic component accurately, the natural component must be identified and subtracted.

A bit of a departure here in this chapter, as we are not dealing with astronomical objects per se but rather various phenomena that are seen in the night sky. Some of these glows are in our Earth’s atmosphere, while others are out in the Solar System itself. Each of them is pretty amazing to see and photograph but does require special conditions and/or
