Abstract

The Sun-Earth Lagrange point L4 is the most stable location among the five Lagrange points at 1 AU. The L4 mission affords a clear and wide-angel view of the Sun-Earth line for the study of the Sun-Earth, Sun-Moon, and Sun-Mars connections from remote-sensing observations. The L4 mission will significantly contribute to advancing heliophysics science, improving the capability of space weather forecasting, and extending space weather studies beyond near-Earth space. This presentation outlines the importance of L4 observations and advocates comprehensive and coordinated observations of the heliosphere at multi-points including other planned L1 and L5 missions. In addition, conceptual designs are provided for an optical telescope for solar H-alpha and photospheric magnetic field observation, and a EUV telescope for solar corona.
