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.

Chasing solar storms as an early career scientist

Hello! My name is Erika Palmerio and I am a newly qualified Dr in space physics from the University of Helsinki, Finland. In this blog post I will talk about my PhD research and my future career plans. The title of my PhD dissertation is “Magnetic structure and geoeffectiveness of coronal mass ejections”. Coronal mass ejections (or CMEs) are huge and spectacular clouds of magnetic field and plasma that regularly erupt from the Sun and travel throughout the heliosphere (that …

Current issue of the EGU newsletter

This month the EGU announced the results of the autumn 2019 elections, which included selecting the Union’s next President, General Secretary and Division Presidents. We also opened two calls for geoscience teachers: one to attend a GIFT workshop in March that will be held in conjunction with the 36th International Geological Congress in Delhi, India, and a second for university-level geoscience teachers to attend a teaching focus group meeting associated with the 2020 General Assembly.

Please remember that the deadline for abstracts for the General Assembly is 15 January 2020 at 13:00 CET. Before then, consider renewing your EGU membership to be part of Europe’s largest geosciences union. EGU members are eligible to submit an abstract to the General Assembly and enjoy substantially reduced meeting registration rates, among other benefits.

Applications are now open for the EGU General Assembly Mentoring Programme (deadline: 31 January 2020).
