Abstract
A method has been developed to search for pulsed and/or unpulsed ultra -high-energy (UHE) emission point sources over a range of time scales. This method has been applied to data accumulated with the CYGNUS exte nsive air-shower array to search for episodic emission from Cyg X-3, H er X-1, the Crab Nebula, and a collection of 48 secondary source candi dates. An examination of timescales ranging from minutes to years has yielded results consistent with background fluctuations.
