An underground muon detector was used to search for periodic changes in the cosmic-ray flux over a 5.4 yr period terminating in 1983 May. Primary cosmic rays with a median rigidity of 1.5 × 10 12 V produced a 4.4 Hz muon rate. The Fourier transformed data show a peak at the sidereal frequency with relative amplitude (3.2 −0.6 +0.8 ) × 10 −4 , which after correction for solar motion with respect to the local interstellar medium indicates an anisotropy of (5.3 −0.7 +0.8 ) × 10 −4 at R.A. 3. h 2 ± 0. h 5.
