AB: Large-scale magnetic fields in 2003 October-November have been calculated using a potential field source surface model in order to study the fast halo CMEs occurred in this period. The calculation shows that these CMEs were associated spatially with open field areas or occurred at the boundaries of two open field regions with like magnetic polarity. We investigate possible relationships between such configurations of magnetic field and fast halo CMEs here. SOHO is a project of international cooperation between ESA and NASA.
