The United Nations is holding a Symposium on Data Analysis and Image Processing for Space Applications and Sustainable Development: Space Weather in Graz, Austria, from 18 to 21 September 2012. This is the first event in a new series of annual symposia that will address the use of space-derived data analysis and image processing tools in support of sustainable development. Organized by the United Nations Office for Outer Space Affairs (UNOOSA), in cooperation with the Government of Austria and supported by the European Space Agency (ESA), the 2012 Symposium focuses on Space Weather data, a timely topic in light of the predicted maximum solar activity during the 2012-2013 period, and the impact that it could have globally. It aims at promoting an active cooperation among the various data collection networks, easier use of specific data collections for better understanding of space weather and solar-terrestrial interactions, and identification of joint activities at the international level in leveraging space weather data.
