We present in a concise statement the newresults based on spectral-polarization measurements ofmagnetic fields in an extremely powerful proton solarflare on October 28, 2003 of X17.2 / 4B class. Theobservation material was obtained with Echellespectrograph of HST AO KNU, which makes it possibleto analyze the spectral manifestations of the Zeemaneffect in very many lines of the visible region of thespectrum, including the photospheric and chromosphericlines. The I ± V and V profiles of about ten
