AFGL5376 is a prominent IRAS 25 \mum source near the Galactic Center. It is associated with a large scale shock that coincides with the western edge of the radio continuum Galactic Center Lobe. There is no evidence for nearby star formation. The unusually warm (T~100 K) dust emission is clearly associated with high velocity ¹²CO(2-1) emission which surrounds the observed infrared peak. We present 350 \mum continuum observations of this region, obtained with the Caltech Submillimeter Observatory facility instrument SHARC II. The observations show strong submillimeter dust emission which is well correlated with the molecular line emission, indicating the presence of a significant amount of warm dust. We discuss possible scenarios which lead to the presence of the large scale shock and to the heating of the associated interstellar medium.
