(Proc. Astron. Soc. Australia). The Hα-flare on 1968 August 23d23h45m was followed by a short-lived type II burst. The radio spectrograph record obtained at Culgoora is shown in Figure 1. The type II burst was of split-band structure with unusual spectral features in each component of the split band. The most remarkable one is an absorption feature between 23h52m02s and 23h52m10s: suppression of the bright type II emission along an ‘inverted U’ (between 120 and 85 MHz).
