A Rotating Solar Magnetic 'Dipole'Observed 1926-1968.

摘要

A recurring pattern with a period of 26 7/8days observed in the polar geomagnetic field during 1926to 1941appears to persist in the interplanetary magnetic field polarity observed with spacecraft during 1963to 1968. This suggests the existence of a rotating solar magnetic 'dipole'with a period of 26 7/8days plus or minus 0.003days. (Author)
