H-alpha monitor-telescope was made and installed as well as hardware and software for the ATsU-26 telescope pointing and guiding. 3-channel slit-jaw imaging system was installed; it allows to obtain images of a part of the Sun, where the telescope is pointed, in Ca K and H-alpha lines as well as in 'white light'. Multiwavelength investigations of solar flares in a wide range of altitudes (from temperature minimum to corona) were carried out with help of observations made in previous years. Physical state of photosphere before onset and on the beginning of solar flares was studied with help of data obtained from space and ground based observatories. Numerical modelling of Ba II 455.4 nm line formation in solar atmosphere was done and accuracy of doppler velocities measurements with aid of this line was analyzed.
