Press release: Göttingen astrophysicists develop European space weather early warning system


Nr. 103/2011 - 11.05.2011


Scientists aim to avert technical disruption in the event of solar storms

(pug) Severe solar storms can disrupt the smooth operation of technological systems on earth, or even cause them to fail completely. Electric power outages of longer duration or disruptions of satellite navigation and communication are particularly critical in this context. In the coming years, scientists at Göttingen University are consequently aiming to develop a prototype for a European space weather early warning system. Specifically, the early warning system is intended to safeguard the operation of telecommunication and navigation systems on earth. Under the direction of the Göttingen astrophysicist Dr. Volker Bothmer, institutions and enterprises in Germany, Belgium, Norway, the Ukraine and the USA are collaborating. The European Union is granting almost two million euros in support of the project. The entire project funding amounts to more than 2.5 million euros.

Solar storms are a consequence of extremely rapid gas eruptions in the sun’s atmosphere, at speeds of up to ten million kilometres per hour. Within one day these storms can cover the approximately 150 million kilometers to reach the earth, where they become visible in the form of polar lights, for example. The scientists are predicting maximum levels of sun activity for 2012 and 2013. In order to develop an early warning system by that time, they are analysing space weather data from space missions currently in operation: NASA’s STEREO, SDO and ACE missions, ESA’s mission Proba 2, and the international space station ISS. Using model calculations and computer simulations, they aim to forecast the arrival of severe solar storms and their expected impact with the highest possible degree of reliability, so that measures to secure the technology at risk in Europe can be implemented in time. This work is being carried out using high temporal resolution 3D mapping of the distribution of electron density in the earth’s upper atmosphere which the University of Göttingen together with the German Aerospace Centre will be making available online.

In addition to the University of Göttingen, partners in the project “Advanced Forecast For Ensuring Communications Through Space (AFFECTS)” are the German Aerospace Centre in Neustrelitz, the Fraunhofer Institute for Physical Measurement Techniques in Freiburg, the firm Astrium ST in Friedrichshafen, the Planetarium Hamburg, the Royal Observatory of Belgium in Brussels, the Institute of Geophysics of the University of Tromsø in Norway, the Ukrainian Space Research Institute, and the Space Weather Prediction Center of the USA National Oceanic and Atmospheric Administration. The administrative project management will be carried out by the EU Office at the University of Göttingen in cooperation with the project director.
