✦ Synopsis

Plasma motions at the initial phases of flares observed in the high resolution soft X-ray spectrometers are summarized. Blue-shlfted components of highly ionized metal ions suggest a senarlo of chromospheric evaporation. A large line width before and during hard X-ray bursts results from a superposltion of multiple directed plasma motions or a turbulent motion directly connected to the magnetic reconnectlon. A further study with an increased sensitivity of the detector should be necessary in the next solar activity maximum.
