Abstract:

Observations at 3.3 mm of the radio source Sagittarius A have been used to obtain a flux estimate. The value is approximately half that predicted by extrapolation of results at longer wavelengths. The mean half-intensity diameter of Sagittarius A appears to be smaller supporting the suggestion of Maxwell and Taylor that the apparent size of Sagittarius A decreases with increasing radio frequency.
