The propagation of Coronal Mass Ejections
Analysing 6 events using in-situ data at 1 AU and 1,5 AU.


The sun is not a quiet place, and when the sun is at its most active state, several tons (~10^12) of hot plasma is ejected a couple of times every day. These are called Coronal Mass Ejections (CMEs), and they can have a massive impact on the geomagnetic field surrounding the Earth.
In this thesis a series of 6 event occurring, in the summer of 2000 has been located using in-situ data at the Earth and the NEAR spacecraft. The orientation and rotation of these events are being analysed, and the overall properties of the events has been listed.
