Resumo

Observations of McMath region 10433 at 22 GHz using a telescope with a 4′ beam during July 1974 revealed the existence events or 'microbursts' with intensities below the sensitivity limit of normal solar patrol instruments. Many of these events were simply the high frequency counterpart of more intense bursts observed at lower frequencies. This note considers the small number of events which suggest that the gyro-synchrotron mechanism alone is incapable of explaining the observations and indicates that a thermal mechanism is needed to explain the high frequency event. © 1976 D.
