- Abstract
We reconstruct the three-dimensional geometry of erupting filaments using observations from different viewpoints. True kinematic evolution of different locations along the main bodies of filaments is investigated. For the erupting filament on 2009 September 26, the highest point is the fastest in the first half hour, and then the points at the low-latitude leg of the filament become the fastest. However, for the event on 2010 August 1, the highest location always has the largest velocity and acceleration during the eruption process. The propagation of EUV enhancements at the endpoints of the erupting filament is observed dearly, which is attributed to the successive down-flows along the different groups of thread-like structures of the filament. Both the two filaments show non-radial eruptions and move towards low-latitude region. Their latitudinal variation is greater than the longitudinal.
