Abstract
The direction to the radio source Sagittarius A is found to be within 0°.03 of the direction to the galactic centre as determined from a number of precise optical and radio observations, including the recently discovered rapidly rotating disk of neutral hydrogen around the centre. This, together with the fact that the source is unique among the known sources, makes it highly probable that Sgr A is situated at the centre. Additional evidence comes from the observation of 21-cm absorption lines, which indicate that the distance of Sgr A is equal to or greater than the distance to the galactic centre.
