The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan

SagittariusD (Sgr D) is one of the oldest known objects from the dawn of the radio astronomy in the Galactic center (GC). It has been considered a complex of HII regions. However, recent radio-continuum and infrared studies indicate that several components at various distances are projected along the same line of sight. In this presentation, we report the Suzaku discovery of a supernova remnant in the Sgr Ｄ complex, overturning the long-standing view of the object for 30 years (Sawada et al. 2009, PASJ). Our work is a nice illustration of the Suzaku's superb sensitivity for faint diffuse sources, which continues to revise our view of the GC region.
