The 8th LOFAR Data School will take place from 16–23 September 2026 at ASTRON, the Netherlands Institute for Radio Astronomy, in Dwingeloo, the Netherlands. The registration is now open at: https://acme-lds2026.sciencesconf.org/

Participants will learn about generating and analysing LOFAR science-ready data. The programme focuses on hands-on experience with interferometric and beamformed observations. We will discuss key science cases including imaging of extended faint sources, exoplanet searches, analysis of solar emission, and pulsar and high time-variability studies. Additionally, we will present an overview of the LOFAR2.0 upgrade and discuss the new scientific opportunities that this enhanced facility will enable.

This edition will run from Wednesday to Wednesday, including a weekend. One of the weekend days will feature an excursion to LOFAR.

Practical details
