Abstract:

In examining the cosmic ray intensity between successive solar minima, it has been noted that the intensity at 1 AU was slightly higher between the 19th and 20th solar cycles i.e. 1965 and between the 21st and 22nd solar cycles i.e. 1987 than between the 20th and 21st solar cycles i.e. 1976. The fact that the galactic cosmic ray intensity in the mid 70s did not return to the levels observed at the other two solar minima is attributed to increased solar activity throughout the 1976 solar minimum period.
