Observations of local sources of the Sun activity at 94 GHz with the radiotelescope RT-2

The importance of study of active formations on a solar disk at the 3-mm wave range is considered. The opportunity of assignment of parameters of active formations-their coordinates, spatial sizes and radio-bright temperature-is shown for observations on radiotelescopes with small aperture at the expense of processing the obtained results using nonlinear iterative methods. The results of restoration of active formations and connection of their spatial parameters with magnetic fields in active areas are given. The preliminary results of research of activity of the Sun in the initial period 23 cycle are given
