Abstract


The solar Type II radio bursts observed with the UTR-2 radio telescope in the 10-30 MHz frequency range are shown. They possess a fine structure consisting of fast-drifting sub-bursts similar to Type III bursts. The Type II bursts frequency drift rate at decameter wavelengths is smaller than –0.1 MHz/s. One burst reveals а herringbone structure with a wave-like back-bone which almost does not drift. The features of the observed bursts are discussed.
