MINOS Observations of Shadowing in the Muon Flux Underground
arXiv:0710.1617
Abstract
A high significance observation of two muon signals, the shadow of the sun and moon, have been seen by the \unit[5.4]{kt} MINOS Far Detector, at a depth of \unit[2070]{mwe}. The distribution of angular separation of muons near the moon was well described by a Gaussian, which was used to determine the angular resolution ($0.34^{\circ}\pm0.07^{\circ}$) and pointing ($0.3^{\circ}\pm0.05^{\circ}$) of the detector.
