抄録
内容記述 The position and size of several wide band bursts of long duration have been studied using 4000 and 9100 Mc/s EW 8-element interferometers and the spectra of many microwave bursts of both long and short durations have been investigated using single frequency observations made at 1000, 2000, 3750, and 9400 Mc/s. The sources of the long-lived, broad-band and intense bursts at cm wavelength scarcely move and their positions coincide fairly well with those of the associated flares. Their heights above photosphere are not so high as those of the Type IV bursts at meter wavelength and it seems that the cm wavelength bursts occur in the lower part of coronal condensation. The size of the sources is less than 4 minutes of arc. The long-lived, broad-band and intense burst on 1000-9400 Mc/s range is not the extension of Type IV burst at meter wevelength. There seem to be two types of long-lived bursts. One is the 'cm wave burst' which has peak intensity near 9400 or 3750 Mc/s, flux density decreases with decreasing frequency and sometimes extends below 1000 Mc/s. The variation with time of intensity is smooth and similar at all frequencies. The other is the 'dm wave burst' which has peak intensity near 1000 Mc/s and usually becomes very weak above 3750 Mc/s. The dm wave burst may be a new distinctive type which is characterized by a comparatively large variability and a very large degree of polarization. It is probable that the source of dm wave burst is different from the source of cm wave burst. There also seems to be two types of short-lived bursts which are similar to those of long-lived bursts on 1000-9400 Mc/s range.
