(left) Full sun 17GHz map. The flare region is indicated by the solid box. (right) Partial 17GHz image. Color map shows brightness temperature, contour shows (r-l)/(r+l) levels, where 'r' and 'l' indicates right-hand and left-hand polarity, respectively. Contour levels of the thick lines are (r-l)/(r+l)=-0.1,-0.2,.. and those of the thin lines are (r-l)/(r+l)= +0.1,+0.2,...
