LOFAR for Space Weather: Evolving the System Design The LOFAR4SW design, being undertaken under a Horizon2020 design study project, is developing rapidly following a recent Science and System Definition Workshop, and is now being prepared for the Preliminary Design Review.

Pieter Benthem (benthem@astron.nl), Mario Bisi (UKRI), Richard Fallows (ASTRON) The LOFAR4SW design study addresses all conceptual and technical aspects required to upgrade the LOFAR radio telescope, systemwide, to take on a parallel role as a highly innovative new facility that enables largescale monitoring projects generating unique data for the European (and worldwide) space weather research community, offering great potential for improved precision and advance warning of space weather events affecting crucial infrastructures on earth. The main goal of the Science and System Definition Workshop, hosted in Cardiff, 1720 September 2018 was to to translate the LOFAR space weather use cases into science and system requirements. The workshop was hosted/organised by UKRI (formerly STFC). There were a total of 21 participants from across all partners. A photograph of the majority of the participants can be found as figure 1.
