| Abstract: | We report here on preliminary results of a systematic study of fast temporal fluctuations in  impulsive and extended solar X-ray bursts observed by PHEBUS at energies around 100 keV. Subsecond timescales are quite common in the impulsive events and are not observed in extended ones. |
