Identifiersolar-aNamesSpace weather Observations at L1 to Advance Readiness - ASOLAR-A About identifiers

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 will also host the EPSI partner contributed instrument. Continuity for SWFO-L1.
