Paper Abstract

Two dimensional spatial variations of the night sky in the visible spectrum have been observed at the focal plane of the 48-inch telescope at Cloudcroft, New Mexcio. A calibrated, slow-scan, intensified television type sensor was used with exposure periods of the order of one second. It is believed that these sky brightness variations are not readily observed with film because of temporal smoothing which accompanies the very long exposure periods needed to achieve comparable brightness threshold levels. In this paper, instrumentation and test data are described, and speculations are made on the origin of the sky brightness variations and on the impact on future systems.
