Abstract
The pulsed radio source discovered at 3·68 m wavelength1 has been studied at various other wavelengths between 2 m and 73 cm2,3. The latter report states that the individual pulses have widths of about 35 ms with a sharp leading edge and with some indication of a second peak near the end of the pulse. Peak flux densities of about 50 flux units are reported by both groups, with time-average fluxes of a few tenths of a flux unit (that is, a few times 10-27 Wm-2Hz-1). At shorter wavelengths, upper limits of 0·1 flux unit were obtained by Ryle and Bailey at 21·4 cm and by Davies et al. at 11·1 cm.
