| Zusammenfassung |
| Coronal Mass ejections (CMEs) are enormous eruptions of magnetized
plasma expelled from the Sun into the interplanetary space, over the
course of hours to days. They can create major disturbances in the
interplanetary medium and trigger severe magnetic storms when they
collide with the Earth's magnetosphere. It is important to know
their real speed, propagation direction and 3-D configuration in
order to accurately predict their arrival time at the Earth. Using
data from the SECCHI coronagraphs onboard the STEREO mission, which
was launched in October 2006, we can infer the propagation direction
and the 3-D structure of such events. In this review, we first
describe different techniques that were used to model the 3-D
configuration of CMEs in the coronagraph field of view (up to
15 R⊙). Then, we apply these techniques to different CMEs
observed by various coronagraphs. A comparison of results obtained
from the application of different reconstruction algorithms is
presented and discussed. |
