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.

Current issue of the EGU newsletter
In our October issue, we are very excited to announce the launch of a new Division, Geoscience and Society! On a more somber note, we also commemorated the 60th anniversary of the Aberfan Mining Disaster with a guest post written in English and Welsh by Rhian Meara. Lastly the EGU27 call for abstracts is open, with the deadline for travel grants and support on the 1 December 2026.
All this and much more, in this month's Loupe!
