Abstract
We report on the simultaneous observation of atmospheric Cerenkov ligh t by a prototype five telescope array, GRACE (Gran Sasso Air Cerenkov Experiment) with deep underground muons in the MACRO (Monopole Astroph ysics and Cosmic Ray Observatory). The telescope array was deployed at Campo Imperatore above the Gran Sasso Laboratory for a run completed in the fall of 1992. The total live time for the combined surface-unde rground operation was similar to 100 h during which more than 300 even ts were seen in coincidence. The efficacy of this technique to monitor the electromagnetic and penetrating muon components of a cosmic-ray-i nduced cascade is discussed.
