The observation of 3.3-mm bursts and their correlation with soft X-ray bursts

Observations of 3.3-mm bursts show that in most cases these bursts have slower rise times and are longer lived than the impulsive centimeter bursts. There is a good temporal correlation between the 3.3-mm and soft X-ray bursts, indicating that these bursts have their origin in the same thermal source mechanism, although these emissions may not arise from the same electrons.This work was supported by the U.S. Air Force under Contract No. F04701-69-C-0066.
