The preflare plage spectra were obtained with the ATsU-26 solar telescope mounted 1 at the Peak Terskol The spectra were acquired from 1 h to 20 min before the flare onset. The most prominent peculiarity of all the observed events are the tilted Ha-emission details which appeal less than 40 min before the flare. This result may testify to spiral structure of the ascending Ha loops The ascending velocities in the chromosphere attain more than 10 km/s Two crossing Ha loops were observed to interact before In flare. As a result of their interaction, the redistribution of velocities occurs in the both chromosphere and photosphere This can be a consequence of the preflare reconnection at the lower atmospheric layers. As the flare onset approaches the ascend of photospheric material start to dominate. The preflare line-of-sight velocities exceed considerably those in the neighbouring unperturbed regions.
