Since its launch in 2001, the Odin satellite has been observing the Galactic Centre Sgr A Complex (CND, +20 and +50 km s<sup>−1</sup> Clouds) as well as the nearby star formation region, Sgr B2, a number of times. Observations have been made in the 118-119 GHz and 486-581 GHz bands. A limited mapping of the Sgr A Complex in the H<sup>16</sup><sub>2</sub>O line has been performed and new observations of the H<sup>18</sup><sub>2</sub>O line took place in 2006. In the 118-119 GHz band, a strong line of HC<sub>3</sub>N (J 13 - 12) has been detected at a number of positions - sensitive upper limits have been obtained for the O<sub>2</sub> (1<sub>1</sub> − 1<sub>0</sub>) and the SiC (3Π<sub>2</sub>, J 3 - 2) lines. Towards Sgr B2, submm observations have yielded absorption profles of H<sup>16</sup><sub>2</sub>O, H<sup>18</sup><sub>2</sub>O, H<sup>17</sup><sub>2</sub>O, NH<sub>3</sub>, and <sup>15</sup>NH<sub>3</sub>. |
