RATAN-600 data.
Table 1.
Fig.3 On the upper
picture an example of one-dimensional
multiwave solar scan with knife diagram pattern at wavelength 3.21 cm is
presented. Intensity scan I=I(L)+I(R) in red line, and circular polarization
scan V=I(L)-I(R) in blue line are shown. The estimation of magnetic field on
the base of cyclotron mechanism for each big source are written nearly
(according method in Akhmedov et al., 1982). Below the multiwave scans in the
range from 1.8 cm to 17.1 cm in Intensity (left) and circular polarization
(right) are presented. The regular RATAN-600 data one can find at

Fig.8 An example of polarization microburst
emission at several decimeter waves,
which manifestates the energy release processes in a cusp of active region.
High temporal resolution needs for adequate study of such structure.
Fig. 9 An example of decimeter microburst emission
after the flare X1.7 at 10h 15m UT in
AR 9393 with 8 minute cadence. The
microbursts were appeared 1.5 hour before and disappeared 0.5 hours after the
flare
