Abstract
A shadow of the Moon, with a statistical significance of (Formula presented) has been observed in the underground muon flux at a depth of 2090 mwe using the Soudan 2 detector. The angular resolution of the detector is well described by a Gaussian with a sigma (Formula presented) The position of the shadow confirms that the alignment of the detector is known to better than (Formula presented) and has remained stable during ten years of data taking.
