โœฆ Synopsis

Observationally solar X bursts fall into three different categories: soft X bursts (E ,< I 0 keV), deka-keV bursts (10-150 keV), and very hard X bursts or deci-MeV bursts (200-1000 keV). The first kind is quasi-thermal, the last kind is non-thermal. The real existence of the third kind of burst looks probable but has not yet been proved by direct observations. The difference between deci-MeV and deka-keV bursts may mainly be a matter of geometry of the emitting plasma.

Hard X-ray bursts have been observed from two 1B flares located in the same sunspot region and separated in time by about 70 min on 8 December 1970. The bursts are composed by many 'flashes' of 2 to 20 seconds duration. Power spectrum analysis reveals no strong periodicities although a significant p
