Abstract Solar-A is a Japanese solar physics mission of JAXA, formerly ISAS (Institute of Space and Astronautical Science) at the University of Tokyo. The overall objective is the study of high-energy phenomena on the sun's visible disk (solar flares, dynamics of solar corona and active regions with focus on time and spectral resolution) through X-ray observations and energetic neutrons (part of gamma-ray region). Primary science objectives are: a) to further the understanding of the magnetofluid dynamics of the repeated expansion of the solar corona, b) clarification of the changes in the shape of the solar corona, and c) the study of the mechanism underlying the occurrence of plasma disturbance phenomena in interplanetary space.

From project initiation in the 1982-1985 timeframe, Solar-A was planned by ISAS as an international collaborative mission with US (NASA) and UK (MSSL, RAL) partners.
