Friday 20th June will be dedicated to a “State of the Union” session, including an overview of the SunPy project, lightning talks from the community (i.e. attendees), project updates, and a broader discussion of the SunPy roadmap.
Participation from both long-time contributors and new community members is highly encouraged. We particularly welcome attendees from instrument teams developing user tools and data pipelines as well as researchers using sunpy for solar data analysis in their workflows.

Lightning Talks#
Lightning talks are short (5–7 minute) presentations from members of the SunPy community, designed to highlight new tools, projects, ideas, or even open questions. They’re a great way to share your work, spark discussion, and connect with others working in similar areas.
The exact timing of each talk will be confirmed soon and posted in the final agenda.
