EXPERIMENTS WITH MONOCHROMATIC ALL-SKY CAMERAS
Abstract
Several optical systems for observing monochromatic emissions with an all-sky camera are described and discussed. They were tested at wavelengths 5577, and 3914 A and should also be useful at 5893 A. They appear capable f gathering useful data but with ordinary fast films require exposures of half an hour or more. New films with tenfold greater speed may reduce this limitation. A preliminary investigation of twilight fluorescence in the 3914 A band of N2(+) suggests that it is only present during auroral activity. (Author)
