Abstract
Transit observations of Centaurus A with a fan beam 1'�5 wide at 73 cm show that the north-eastern component of the central source has an east-west width of 1'�7 and that the south-western source has a width of 2'�3. Since the situation at 9�1 cm is roughly the reverse of this, the two components must have sharply different spectra. The right ascensions observed are 13h 22m 48s . 0 and 13h 22m 20s�2�os�2 (1950). The right ascension of the centre of NGC5128 has been separately determined as 13h 22m 31s�6�os�3, showing that the two components are at significantly unequal distances from the optical object.
