Abstract
The paper discusses the development of an instrument to collect sky luminance data over an extended period of time and store it on cassette tape. Data are collected automatically by positioning a photometer using stepping motors under microprocessor control. The instrument consists of five major components: a power supply, positioning hardware, photometer, interface hardware, and microcomputer. The elevation motor and photometer sight tube and sensor are located on the elevation support assembly. All other components are housed in a based assembly. The instrument may be carried by one person. The instrument is operational and is currently being tested on the roof of the engineering building at the University of New Hampshire.
