Division on Solar-Terrestrial Sciences

President: Olga Malandraki (st@egu.eu)
Deputy President: Margit Haberreiter (margit.haberreiter@pmodwrc.ch)

The ST Division considers all aspects of solar and heliospheric physics, specifically the solar-terrestrial connection. It covers the physical processes occurring on the Sun, in the solar wind, as well as in Earth's magnetosphere and ionosphere. Solar activity (e.g. coronal mass ejections, solar flares, solar energetic particle events) and the response of the near-Earth space environment to these solar phenomena are studied on a wide-range of temporal and spatial scales. Data analysis and interpretation of space-borne and ground-based data, as well as theoretical studies and different modeling techniques are used to better our understanding of how our local star defines the neighborhood that we live in.

Current issue of the EGU newsletter

This month the EGU held its first science-policy pairing scheme, during which a Union member provided scientific testimony and worked alongside a Member of the European Parliament for two days in Brussels. We also published a new policy report summarising the key outcomes from EGU's 2019 science policy event, Shaping EU Missions: bridging the gap between geoscience and policy, held in Brussels in October.

In other news, we have opened the call for applications for EGU Public Engagement Grants (due 15 February 2020) and for EGU Galileo Conference proposals (due 29 February 2020). We also announced a job vacancy at the Union office for a Chief Strategy & Finance Officer. The deadline for applications is 8 January 2020.

If you’d like to apply for funding to support travel to the General Assembly next year, please submit your conference abstract by 1 December 2019.
