The Division on Solar-Terrestrial Sciences (ST) 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 modelling techniques are used to better our understanding of how our local star defines the neighbourhood that we live in.

The 2024 Division Outstanding Early Career Scientist Award is awarded to Erika Palmerio for outstanding research in analysing complex solar transients and their space weather effects.
The 2023 Julius Bartels Medal is awarded to Hermann Opgenoorth for his exceptional contributions to substorms and space weather research, and his strong leadership in international collaboration.
The 2023 Division Outstanding Early Career Scientist Award is awarded to Stephan G. Heinemann in recognition of his outstanding research in the field of solar terrestrial relations and solar physics.
The 2023 Outstanding Student and PhD candidate Presentation (OSPP) Award is awarded to Artem Smirnov Neural network model of Electron density in the Topside ionosphere (NET)
The 2023 Outstanding Student and PhD candidate Presentation (OSPP) Award is awarded to Veera Juntunen Influence of geomagnetic activity on the wintertime electricity consumption in Finland via Northern Annular Mode
Particle Precipitation High energy particles (e.g. electrons and protons) that precipitate at high latitudes can alter the chemical composition of the atmosphere by different photochemical reactions. This mainly happens due to primary collision processes and subsequent ion and neutral-chemistry reactions. Such reactions ordered by increasing energy are, for example, excitation, photo-dissociation, photo-ionization and dissociative ionization. These particles can come from various sources in outer space, accelerated by different processes to varied energies, and they affect different altitude ranges of the …
Life in academia can be complex, involving handling multiple roles while developing and sustaining a successful career. Therefore, it can be challenging to balance research responsibilities with other commitments. Understandably, effective time management is essential for researchers to be productive and to achieve their goals, without sacrificing other important matters in life. The Early Career Scientists (ECS) team of the Solar-Terrestrial (ST) division of the European Geophysical Union (EGU) is organizing a campfire event to discuss this matter. In this …
How do you get more people to care for the geosciences – a field that affects and influences all of life itself? Scientists across the EGU network share their stories!
Friedrich Barnikel outlines how, since 2003, EGU brings together scientists and teachers for capacity-building workshops, while Evi Nomikou takes us through EGU’s third Geoscience Day, highlighting volcanic geohazards to over 260 school students.
We also hear from Grace Skirrow who breaks down a seemingly complex subject like fluvial geomorphology and the role that it can play in policy decisions. Meanwhile, geologist Sinelethu Hashibi explains why she’s driven to translate geoscience for isiXhosa-speaking communities. And for those of you fond of card games, don’t miss the launch of QUARTETnary: a game about the geological time scale, developed by Iris van Zelst and Lucia Perez-Diaz and partly funded by the EGU Public Engagement Grant 2021.
