The Solar-A Mission and Its Scientific Aims

Descriptions of the scientific instruments on board the Solar-A satellite are given. Relevant parameters and merits of the Solar-A experiments, consisting of co-aligned soft and hard X-ray telescopes with high sensitivities and spatial resolutions, together with Bragg and wide-band spectrometers, are presented. Some of the observational targets, both flare related and non-flare-related are discussed together with brief solar physical implications of these observations. The importance is stressed for collaboration with the ground-based optical and radio observatories to maximize the scientific outcome from this small but unique satellite for the investigation of flares during the solar activity maximum 22.
