Abstract Flux limits in the range 10-13 to 10-12cm-2s-1 have been obtained by observing Cerenkov flashes from small air showers. Simultaneous drift scans by the 67 mirror units of the Utah Fly's Eye gave nearly full coverage of the northern hemisphere. During 1983, a 3.5 σ excess of showers was observed during the phase interval 0.2 - 0.3 of the 4.8 hr period of Cygnus X-3, but no excess was found in 1984 observations.
