FOLLOWING the discovery by the X-ray astronomy group at Leicester University of a large increase in the X-ray flux of A0620-00, observations at 962 MHz and 151 MHz have been made at Jodrell Bank. During the period August 16-29, observations were made at 962 MHz with the MK II-MK III long baseline radio-link interferometer. This instrument has a spacing of 23.7 km giving a lobe size of ∼ 3″ at this frequency. The radio-link is phase compensated so that integrations can be made for several hours.
