Observations of the Galactic Nucleus at 350 Microns

We have observed the regions in the galactic center in the far-infrared and detected the flux (3.91 t 0.76) x 10-11 W rn-2 from Sgr B and obtained an upper limit 1.5 X 10-11 W rn-2 from Sgr A, corresponding to flux densities at 350 of (4.3010.86) X 10-22 and 1.6 X 10-22 Wm-2 Hz - 1, respectively. Scanning observations of Sgr B in right ascension indicate that the width of the source is 5'-10'. A close assodation between the far-infrared source and the molecular region in Sgr B is indicated, and an optically thin therinal model for the far-infrared radiation from dust grains is discussed.
