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.

AGATA: Advancing Polar Science through Multi-Instrument Integration and Collaboration
Scientific research has long recognized that solar-terrestrial interactions play a crucial role in shaping the polar atmosphere, impacting both climate dynamics and atmospheric coupling across different layers. Understanding these interactions is key to unraveling their far-reaching effects on Earth’s climate, space weather, and global atmospheric processes. The recognition of these critical processes has driven international research initiatives like the International Polar Year (IPY) programs, which involved thousands of researchers and facilitated global collaboration and data sharing. These efforts have established …

Meet Erika Palmerio, the 2024 Outstanding Early Career Scientist Awardee of the Solar-Terrestrial Division!
Congratulations on receiving the EGU 2024 ST Division Outstanding Early Career Scientist Award for your exceptional research in analyzing complex solar transients and their effects on space weather. What does this recognition mean to you personally, and how does it impact your work in this fascinating field? Thank you so much! Receiving an award from EGU is of particular significance to me, since my very first conference as an early PhD student was the EGU General Assembly in 2016. I …

Current issue of the EGU newsletter
In our March issue we are here to help you prepare for the EGU25 General Assembly, with guides for first time attendees, understanding the EGU Code of Conduct, our playlist of EGU25 walk-through videos, two webinars to help you prepare your presentations and sign ups open for the EGUtoday newsletter, we are excited to get together with you all, in Vienna and online, in less than a month!
This month we also learned about a special scientific landscape under threat and what we can do to help, and now is also your last chance to get involved in the Science for Policy interface in Europe by applying to join EGU's new Climate Hazard and Risk Task Force by 31 March.
For all our talented photographers, the EGU Photo Competition is still open for submissions; enter by 31 March and you could win free registration to EGU26, and the admiration of your peers! All this and much more in this month's Loupe!
