Changes of solar anisotropy and of the intensity of cosmic radiation

Solar and terrestrial relationships of the changes of anisotropy have been studied, and theories have been advanced to explain the creation of the anisotropy by a modulation of cosmic-ray intensity incident at particular directions. The results of the investigation presented are of a preliminary character and indicate certain tentative conclusions which can be drawn from the analysis of data from narrow-angle telescopes operated over a period of eleven months in 1956. One of the most important conclusions is that there is a definite correlation between day to day changes of anisotropy and the daily mean intensity
