<title>Sloan Digital Sky Survey cloud scanner</title>

Abstract

Astronomers have traditionally monitored cloud cover visually. However, this technique is difficult under dark conditions, insensitive to thin cirrus, and impossible for remote telescope use. A sensitive camera operating in the thermal infrared escapes these problems. Unfortunately, commercially available cameras have smaller than desired fields of view, are not intended for continuous operation, and are expensive. Consequently, a single channel all- sky scanner has been constructed to continuously monitor observatory cloud cover and motions. Operating at a wavelength of 10 microns, it produces a 135 degree(s) X 135 degree(s) image with a resolution of 0.9 degrees. These data are suitable for returning to remote observers and for archiving with astronomical data.
