PULSARS were first detected successfully at centimetre wavelengths by Moffet and Ekers1,2. Seven pulsars, CP 0328, PSR 0833, CP 0950, CP 1133, JP 1933, AP 2015 and PSR 2045, have now been observed at a wavelength of 12.5 cm (2,388 MHz) using an 85 foot azimuth–elevation antenna of the Goldstone Tracking Station in California. Observation of three of these, CP 0950, CP 1133 and AP 2015, was attempted at 3.5 cm (8,448 MHz) using the same antenna. The data recorded in the observations were analysed to determine the level of activity of each pulsar averaged over several weeks. The results of this analysis are presented here. A detailed analysis of the pulse arrival times and the short-term fluctuations in the pulse energy will be presented elsewhere.
