A portion of the Fly's Eye II detector has been recording Cherenkov flashes since 1987 in the declination band 10° < ä < 50°. This band includes Cyg X-3, Her X-1, the Crab nebula, and Cyg X-1. The threshold energy is approximately 70 TeV. Observed and expected shower counts are available for all points in this declination band on a nightly basis. Searching for steady, transient, or sporadic poi...
