Christian is a PhD student at the University of Graz and the Space Research Institute of the Austrian Academy of Sciences in Graz, Austria. He is modelling multi-spacecraft observations of “magnetic clouds” in the solar wind. These are large-scale magnetic structures, containing helical field lines winding around a straight axis, much like a spiral staircase or the DNA. They are expelled from the Sun as “coronal mass ejections” and are known to cause the most severe geomagnetic storms. The step from single- to multi-spacecraft observations allows recovering global properties of magnetic clouds with increasing accuracy. Particularly, the application to recent observations by the NASA STEREO mission provide new insights into their shape and structure.
