AbstractThe Odin satellite has been used to detect emission and absorption in the 557-GHz H 2 16O line in the Galactic Centre towards the Sgr A Circumnuclear Disk (CND), and the Sgr A +20 km s -1 and +50 km s -1 molecular clouds. Strong broad H 2O emission lines have been detected in all three objects. Narrow H 2O absorption lines are present at all three positions and originate along the lines of sight in the 3-kpc Spiral Arm, the -30 km s -1 Spiral Arm and the Local Sgr Spiral Arm. Broad H 2O absorption lines near -130 km s -1 are also observed, originating in the Expanding Molecular Ring. A new molecular feature (the "High Positive Velocity Gas" - HPVG) has been identified in the positive velocity range of ≈+120 to +220 km s -1, seen definitely in absorption against the stronger dust continuum emission from the +20 km s -1 and +50 km s -1 clouds and possibly in emission towards the position of Sgr A CND. The 548-GHz H 2 18O isotope line towards the CND is not detected at the 0.02 K (rms) level.
