Description
The Vigil space weather mission is currently being developed for launch to the Sun-Earth L5 Lagrange point. From this location it will provide low-latency remote and in situ measurements of the Sun and solar wind for operational space weather services. As part of its payload, Vigil will carry a magnetometer to measure the interplanetary magnetic field in situ. A key goal of the Vigil project is to maximise its impact for both space weather operations and science. In this contribution we first describe the current status of the Vigil magnetometer development, and review its expected performance including real-time operational capabilities. We then examine more specifically how Vigil magnetic field data can contribute to scientific and operational use-cases based around its ingestion into heliospheric and magnetospheric space weather models throughout the solar system. In the heliospheric context we investigate how Vigil magnetic field data has the potential to constrain both global and transient interplanetary magnetic field structure, and in the magnetospheric context we explore how it may contribute to the prediction of magnetospheric dynamics at Earth and other solar system bodies.
