Team 4 – Solar eruptive events: tracking flares, CMEs and particles from the Sun to the heliosphere

Solar Orbiter Hackathon (17-21 Nov 2025)

Team goal
We aim to better understand how solar flares and eruptive events accelerate particles at the Sun, and how those signatures evolve through the heliosphere, from remote sensing of the flare/CME to in-situ detection of energetic particles and solar wind/magnetic structures.
We will leverage Solar Orbiter’s combined remote sensing (e.g., EUV, X-ray, coronagraph) and in-situ (particles, fields, waves) capabilities to track the full chain: energy release → flare ribbons/footpoints → CME launch → particle acceleration/transport → in-situ signatures.

🧭 Scope & deliverables

During the hackathon week we’ll focus on:

1. Selecting one or more well-observed flare + CME + SEP events from Solar Orbiter data.
2. Performing coordinated analyses:
   • Remote sensing: flare timing, ribbon / footpoint evolution, CME morphology and kinematics.
   • In-situ: energetic particle time series, magnetic field signatures, plasma/flow context.
   • Linking remote observations to in-situ measurements (timing, propagation, connectivity).
3. Producing notebooks / scripts that perform reproducible analyses (Python + SunPy, etc.).
4. Documenting our workflow and results: summary report (markdown or Jupyter), figures, event timeline, key metrics.
5. (Optional) Preparing a short presentation or poster summarising our findings at the end of the week.
