Abstract. A recurring pattern with a period of 267/8 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 exist...

| Summary: | Abstract. A recurring pattern with a period of 267/8 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 267/8 + 0.003 days. Olsen (1) has discovered a recur-rent pattern with a period of 267/8 days in the horizontal component of the geomagnetic field observed at God-havn, Greenland (corrected geomagnet-ic latitude, 77.5°N), during the years |
