Abstract
AT Toyokawa Observatory we have been mapping the brightness and polarization distribution across the Sun at intervals of 10 s by a quick scanning system installed at the 8 cm radio interferometer since the end of August 1968 (ref. 1). The base line of the 32 element adding interferometer is 213.28 m or 2,666 wavelengths, which corresponds to a half-power beam width of 1.1 min of arc. This letter describes two examples of bursts with double structure which have been observed during the past eight months.
