    Using data collected by the MACRO experiment during the years 1989-1996, we show evidence for the shadow of the Moon in the underground cosmic ray flux with a significance of 3.6σ. This detection of the shadowing effect is the first by an underground detector. A maximum-likelihood analysis is used to determine that the angular resolution of the apparatus is 0.9°±0.3°. These results demonstrate MACRO'S capabilities as a muon telescope by confirming its absolute pointing ability and quantifying its angular resolution. ©1998 The American Physical Society.
