Observations of A0620—00 at 962 and 151 MHz

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.
