DESCRIPTION:Speakers: Irina Bakunina (National Research University Higher 
 School of Economics)\nUnder this study we considered active regions of the
  23-rd an 24-th cycle of solar activity which were observed with the 2D sp
 atial resolution at two frequencies: 17 and 34 GHz with the Nobeyama Radio
 heliograph (NoRH) and we used daily solar observations with the RATAN–60
 0.\n   We detected appearance and rapid development of a compact microwave
  source above the neutral line of the magnetic field (NLS-source) one-two 
 days or few (14–17) hours before the X-class flares. The position of thi
 s source associated with the place of the maximum of magnetic field gradie
 nt at the photosphere.\n   A compact source (NLS) under 2D observations at
  NoRH is characterized by a shift of the centers of brightness in the pola
 rization and intensity before powerful flare. \nIn most cases the formatio
 n of δ-configuration of the magnetic field preceded the detection of NLS.
