Rolling motion in erupting prominences observed by STEREO

► The rolling motion of the erupting filament is away from a neighboring coronal hole. ► The non-radial motion of the associated CME is away from a neighboring coronal hole. ► The erupting filaments were all more non-radial than the CMEs but in the same general direction. ► The rolling motion depends on the level of force imbalances inside the filament arcade. ► The non-radial motion of the CME is related to global magnetic configuration force imbalances.
