Abstract

A coronal oscillation with a changing period was observed with the acousto-optic radio spectrometer of Yunnan Observatory. The bandwidth of the oscillation was about 10MHz. It accompainted radiation which lasted for about 500ms. A corresponding burst was found on a radio spectrogram obtained at Weissenau, Germany. A 245MHz burst was reported at the same time and we found a bright spot on the Halpha film records of Yunnan Observatory. In this paper, we present a series of spectra of the oscillation at 10ms intervals. In the spectra the oscillation appears in the form of a 3.5 MHz drift of radio flux with frequency.
