Division on Solar-Terrestrial Sciences

President: Olga Malandraki (
Deputy President: Margit Haberreiter (

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.

Filmmakers get creative with the sounds of satellite data

One of the major motivations behind research into solar-terrestrial physics is the potential consequences of space weather on our technologically dependent society. Given this risk, recognised by many governments around the world, it is a little concerning that a sizable fraction of the public have never even heard of the term “space weather” – for example a recent public dialogue in the UK showed 48% of the adult population reported this. It is therefore important that we reach out to …

Current issue of the EGU newsletter

Why is research in Antarctica so important? In this issue of The Loupe, EGU asks experts why they think it really matters. We also highlight blogs from each of the month’s featured EGU divisions: Climate: Past, Present & Future, Cryospheric Sciences, and Nonlinear Processes in Geosciences.

This issue also discusses the extensive fee waiver programme for vEGU21. The abstracts submission deadline is 13 January 2021 at 13:00 CET!

Last, but not least: for those scientists who tend to shop late, there’s the Top 5 (last-minute) gifts for geoscientists. From the ultimate sample collection kit to cake (no, really!), EGU has you covered with our last-minute guide. And the #1 gift? You’ll need to read the blog!
