Meetings
The Variable Sun: Past, Present, and Future Perspectives
The Variable Sun: Past, Present, and Future Perspectives will explore solar variability—changes in the Sun's magnetic activity over timescales from days to millennia. It aims to bring together experts in observations, modeling, to discuss recent scientific results. The program will feature invited reviews and invited talks, focusing on understanding solar magnetism and solar variability across various domains

UK Space Weather & Space Environment Meetings
With a UK core, the meeting will be outward looking, where we very much welcome international participation. This is the third in a series of an ongoing meetings based around space weather and the space environment. This in recognition of the spirit of multinational collaboration which needs to be at the heart of enhanced understanding of, and resilience to space weather and the Earth’s space environment.
The long-term purpose of this developing series of UK Space Weather & Space Environment Meetings is to bring together space safety scientists, engineers, forecasters, end-users, and policy makers across the various UK interests and activities. This year’s meeting will have focus on the global challenges in understanding our space environment and space-weather impacts at solar maximum, as well as in seizing opportunities to drive further advances going forward.!

European Space Weather Week 2025
In 2025, the European Space Weather Week will take place in Umeå, Sweden from October 27 to 31. The ESWW is the main annual event in the European Space Weather and Space Climate calendar. It is an international meeting organised annually within the European Region in collaboration with prominent members of the European space weather and Space Climate community. It began as a forum for the European Space Weather community and has since grown into an international event with global attendance.
ESWW2025 will again adopt the central aim of bringing together the diverse groups in Europe working on different aspects of Space Weather and Space Climate: such as scientists, engineers, satellite operators, power grid technicians, communication and navigation specialists, people working in aviation, space weather service providers, STEM* practitioners. The ESWW is highly interdisciplinary by nature and actively promotes investigation of new technologies and approaches e.g. machine learning in a space weather context.
ESWW also welcomes space weather end users. End users constitute any group/organisation making use of space weather data and services. Fields include but are not limited to spacecraft operation, spacecraft design, space and ground based telecoms and navigation services, power distribution, pipeline operation, aviation safety, railway operators, insurance companies, civil contingency planning, and scientists.
ESWW is an excellent place to meet people, to exchange knowledge and ideas, to discuss the latest on solar activity, how space weather influences the earth environment on the short and on the long term and our technologies, and how to deal with space weather.
27 – 31 October 2025 in Umeå, Sweden
Important Dates & Deadline
Oral abstract submissions is 22 May 2025. Past this date, all submissions will be considered for poster presentation only.
late poster abstract submissions will close 5th September 2025.
Data, Analysis, and Software in Heliophysics
ThData, Analysis, and Software in Heliophysics (DASH) meeting serves as a forum for scientists and software developers to present and discuss algorithms, software, and data systems used throughout Heliophysics, including space and ground-based measurements as well as models. The meeting especially aims to connect practitioners and promote collaboration across the international heliophysics software community.
The goal of the co-located International Heliophysics Data Environment Alliance (IHDEA) is to provide the international Heliophysics community the opportunity to collaborate on improving or creating common standards and services to increase the interoperability of our resources and accelerate next-generation science.
Participants of all experience levels are welcome. The program will include invited talks, contributed talks, and a poster session. Virtual attendance is possible, but presenters are expected to participate in person.
Machine Learning in Heliophysics
The goal of the ML- Helio conference is to leverage the advancements happening in disciplines such as machine learning, deep learning, statistical analysis, system identification, and information theory, in order to address long-standing questions and enable a higher scientific return on the wealth of available heliospheric data
We aim at bringing together a cross-disciplinary research community: physicists in solar, heliospheric, magnetospheric, and aeronomy fields as well as computer and data scientists. ML- Helio will focus on the development of data science techniques needed to tackle fundamental problems in space weather forecasting, inverse estimation of physical parameters, automatic event identification, feature detection and tracking, times series analysis of dynamical systems, combination of physics-based models with machine learning techniques, surrogate models and uncertainty quantification.
The conference will consists of classic-style lectures, complemented by hands-on tutorials on Python tools and data resources available to the heliophysics machine learning community.
The conference will be hosted in hybrid mode (in-person and virtual).
