The CYGNUS extensive air shower array has been operating since April,
1986, searching for evidence of point sources
of ultra high energy(UHE) radiation.
For showers initiated by protons, the median
primary energy detected by the array is approximately 100 TeV. The
median primary energy for gamma ray initiated events from a source that transits
at zenith is about 60 TeV. In this paper, the general apparatus setup,
experimental techniques, and
analysis methods will be described.
The results from a survey of the northern sky for continuous emission by point
sources, and a search for episodic emission by 51 candidate
sources on a daily basis will also be presented.
