Skibotn CCD All-Sky Imager

The Skibotn CCD All-Sky Imager (SCASI) consists of a peltier-cooled bare CCD camera fitted to a twin-mirror all-sky optic (180 degree field of view). The main purpose is to perform cloud cover detection in a supporting role for the FPI and DASI experiments. This is done by looking for stars. Images of 30 second exposure are taken every 3 minutes. Of course, the aurora is also clearly seen. Unmanned observations are made for all dark periods.
