标题：L1L5Together: Report of Workshop on Future Missions to Monitor Space Weather on the Sun and in the Solar Wind Using Both the L1 and L5 Lagrange Points as Valuable Viewpoints
摘要：The “L5 in Tandem with L1: Future Space Weather Missions Workshop” was held in London on 6–9 March 2017 to discuss technical and programmatic steps toward an operational system for monitoring space weather conditions on the Sun and in the solar wind. This system would exploit the viewpoints provided by the Sun-Earth L1 and L5 Lagrange points—two locations where we can place spacecraft in quasi-stable orbits with complementary views of solar and interplanetary conditions that could lead to adverse space-weather impacts at Earth. This personal report summarizes the talks and discussions at the workshop—pulling out key issues of likely interest to a wider audience and important considerations on the route to an operational system at L1 and L5, a system that can help to protect societies around the world from the risks posed by space weather.
