Subsector structure of the interplanetary space - SOLSPA 2001

A new conception about the sub-sector structure of interplanetary space is introduced. It is shown that in a potential model of the solar magnetic field there exist direct relations between photospheric regions of open magnetic field lines (ORs) and corresponding magnetic domains at the source surface and the interplanetary magnetic field. These domains generate a large-scale sub-sector structure of the solar and interplanetary magnetic field, with boundaries between domains of the same polarities. Solar, interplanetary, and ground-based observations of 1999-2000 were used to test this conclusion.
