INTERPLANETARY SECTOR STRUCTURE IN THE RISING PORTION OF THE SUNSPOT CYCLE,
Abstract
The interplanetary sector structure during the rising portion of the sunspot cycle in 1966 and 1967 has been investigated. The sector pattern is often quasi-stationary for a few rotations, followed by an appreciable change in the next rotation. When a sector boundary passes the earth, geomagnetic activity tends to increase, an effect rather similar to that observed near sunspot minimum. The recurrence period of the interplanetary field during the interval investigated was 27.5 plus or minus 0.1 days. (Author)
