Search for Point Source of Cosmic Rays

IN order to search for possible point sources of cosmic rays, an alt-azimuth Geiger–Muller counter telescope of narrow angular resolution (5° × 5°) was made, and kept nearly horizontal (zenith distance Z = 80°) so that the effective cosmic-ray particles were free from complicated geomagnetic deflexion. After scanning over the celestial sphere, especially large intensities were observed at two positions as noticed in our earlier paper1.
