The present report gives the several statistical data on the properties of S.D.A. at 10, 21, and 27 kc., which were obtained through two years observations from 1955 to 1956. All of the observed S.D.A.'s occurred in the period from sunrise to 2 or 3 hours after the sunset. The durations of S.D.A.'s were in the time range 1O~50 minuites and their intensities mainly ranged from 2 to 5 db. About 80% of the observed S.D.A.'s accurately had correlations to the outbursts of solar radio emission that were recorded at least at one frequency out of 200, 3000, 3750 and 9400 Mc/s. Though the correlation of the intensity, and the duration, of S.D.A'. s to the intensity of solar radio outbursts is not good, it is concluded that the solar radio outbursts having strong intensity and long duration will accompany S.D.A.'s with high probability.
