It is well known that 27-day recurrent variation of cosmic radiation presents long periods of stability in correlation with long-life high-activity regions of the sun. These variations have been previously studied during the last solar activity maximum (Oct. 1956 to Dec. 1958) using data from two neutron monitors located at Pic-du-Midi, France, and Port-aux-Francais, Kerguelen Island. Results are presented from a study of these recurrent variations for the Jan. 1955 to Jan. 1961 period. (W.D.M.)
