... SHORT TERM PREDICTION OF POWER SOLAR FLARES FROM SSRT DATA . The algorithm for short term prediction of powerful solar flares, based on SSRT data, includes microwave emission characteristics in total and polarized flux, the structure of active region (AR) magnetic field at the photospheric level, and H a patrol data. ... During this period, 7 AR's crossed the solar disk, in which 20 flares of importance ? ... Data on AR's and magnetic fields were received from the Sayan observatory by teletype. ...
