Abstract:

The mean magnetic field of the sun seen as a star during the interval March-June 1968 has an almost complete agreement with the polarity of the interplanetary magnetic field observed near the earth. This agreement could exist only if the solar source of the interplanetary field was part of a field pattern that was ordered over an appreciable portion of the solar disk. The result is consistent with a previously derived solar sector pattern in the weak, large-scale photospheric field in which the boundary between two solar sectors is at almost the same longitude independent of latitude over a range of at least 40 degrees N to 40 degrees S latitude. Comparison of the contribution of sunspot magnetic fields with the mean solar field indicates that the sunspot fields do not have a direct influence on the interplanetary field. Author
