MEASUREMENTS of the angular sizes of radio sources made with a 21 cm interferometer between Jodrell Bank and the Royal Radar Establishment, Malvern, over a baseline of more than half a million wavelengths have already been published1,2. Nine sources were shown to be smaller than 0.1 sec of arc in at least one dimension. During 1966 the performance of the digital fringe speed machine was greatly improved and, in addition to further measurements at 21 cm, observations were made at the shorter wavelengths of 11 cm and 6 cm, the radio telescope Mark II being used in place of the Mark I at Jodrell Bank. At the shortest wavelength the maximum effective baseline is greater than two million wavelengths.
