Abstract

The bright night sky above the Van Vleck Observatory, located on the Wesleyan University campus, has prompted a program to monitor the skyglow visually and photoelectrically for a decade. Portable visual photometers were developed which can measure sky brightness in the field; they show that the skyglow is very local.
