Skolkovo Scientists Develop Method to Study Extreme Space Weather Events

Cluster with two consecutive Coronal Mass Ejections on 9 (left) and 10 (right) September 2017 with speeds of 1148 and 3703 km/s respectively. The event occurred during the declining phase of the 11-year solar cycle n24 and forced the crew onboard International Space Station to move to the station’s shelter to protect themselves from the strong radiation emitted by the largest solar flare observed in the last 12 years.

MOSCOW (Skoltech PR) — Scientists at Skolkovo Institute of Science and Technology (Skoltech), together with colleagues from the Karl-Franzens University of Graz the the Kanzelhöhe Observatory (Austria), Jet Propulsion Laboratory of California Institute of Technology (USA), Helioresearch (USA) and Space Research Institute of the Russian Academy of Sciences (Russia) developed a method to study fast Coronal Mass Ejections, powerful ejections of magnetized matter from the outer atmosphere of the Sun.

The results can help to better understand and predict the most extreme space weather events and their potential to cause strong geomagnetic storms that directly affect the operation of engineering systems in space and on Earth.  The results of the study are published in the Astrophysical Journal.
