The magnetic field of the sun as a star, 1969-1976
Abstract
A superposed epoch analysis of the mean solar magnetic field measured in the Crimea during 1969-1976 was performed using approximately 215 sector boundaries of the interplanetary magnetic field. The mean field displays a sector structure, with a typical field strength within a sector of 0.4-0.3 G. The average magnitude of the mean field decreased from 0.5 G in 1969-1970 to 0.15 G in 1975-1976. The principal recurrence period in the data is 27.04 d + or - 0.06 d. The resulting curve reflects the asymmetry between magnetic fields of opposite sign (the duration of S polarity is 3-4 days greater than that of the N polarity).
