Scientific paper

The relationship between filament eruptions and CMEs has been well established. But the trigger mechanism as well as the overall association between filament eruption and CME is not well understood. Observations obtained with space and ground-based observatories are used to study the photospheric magnetic field evolution and coronal structure changes associated with the filament eruption and subsequent CME. The evolution and eruption are characterized by different stages during which the initial filament structure and magnetic configuration change greatly. Comparison with magnetograms suggests that new magnetic flux emergence and a new active region formation enable the eruption of a filament and subsequent CME by interaction processes with nearby coronal hole.
