New paper published in Nature Communications

An international team of scientists led by Dr.sc. Christian Möstl from the Space Research Institute (Institut für Weltraumforschung, IWF) in Graz, including couple of Hvar Observatory team members, recently published a scientific paper in Nature Communications. The paper Möstl et al. regards the non-radial propagation of CMEs, using a synthesis of data of a fast CME from seven different space missions. CME, which originated in an active region near the disk centre, was forecasted to have a significant geomagnetic impact. However, the CME is demonstrated to be channeled during eruption into a direction away from its source region, leading only to minimal geomagnetic effects. In situ observations near Earth and Mars confirm the channeled CME motion, and are consistent with an ellipse shape of the CME-driven shock provided by the new Ellipse Evolution model, presented in the paper. The results enhance our understanding of CME propagation and shape, which can substantially influence the geomagnetic effects of CMEs. The publication of the paper was covered by several media such as space.com(ENG), the Conversation(ENG), Discovery News(ENG), Sueddeutsche Zeitung(GER), Der Standard(AUT), tportal(CRO).
