A rotating solar magnetic " dipole" observed from 1926 to 1968.
A recurring pattern with a period of 26(7/8) days observed in the polar geomagnetic field during the interval from 1926 to 1941 appears to persist in the interplanetary magnetic field polarity observed with spacecraft during the interval from 1963 to 1968. This observation suggests the existence of a rotating solar magnetic "dipole" with a period of 26(7/8) +/- 0.003 days.
