Dear Colleagues,

We are delighted to invite you to LSST@Europe7, the seventh in the series of LSST@Europe conferences, which will take place in Poznań, Poland, from September 15 to 19, 2025.

Building on the successes of previous conferences in the UK, Serbia, France, Italy, Croatia, and most recently La Palma, Canary Islands, LSST@Europe7 will mark a pivotal moment for the Rubin Observatory community as we focus on the first scientific results obtained with the Legacy Survey of Space and Time (LSST).

• The importance of the first light from Vera C. Rubin Observatory.
• The latest updates from Rubin Observatory's operations and data releases.
• Key science opportunities and discoveries enabled by LSST data.
• In-kind contributions with an emphasis on European-led initiatives.
• Collaborative projects and tools to maximize the science potential of the LSST era.

The meeting will adopt a hybrid format, ensuring broad accessibility for both in-person and remote participants. The venue in Poznań will accommodate up to 300 in-person attendees. Mark your calendars and stay tuned for updates on registration, abstract submissions, and program details.

We look forward to welcoming you to Poznań for what promises to be an inspiring and fruitful meeting.

On behalf of SOC and LOC,
Agnieszka Pollo & Agnieszka Kryszczyńska
