Objectives and Applications Space weather observations along the Sun-Earth line from the Lagrange 1 point, including coronal white light imagery, solar X-ray irradiance using the ESA-provided X-ray Flux Monitor instrument, and heliospheric in situ measurements of solar wind and magnetic field. The spacecraft may also carry an instrument of opportunity. Follow-on and resilience for SWFO-L1.
