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.
