Full sun 17GHz image. The flare region is indicated by the solid box.

Partial 17/34GHz images. Color map shows brightness temperature, contour shows 17GHz (r-l)/(r+l) levels, where 'r' and 'l' indicates right- and left-handed circularly-polarized components, respectively. Field of View is 314. x 314. arcsec
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,...
Orange circle at top-left indicates the half-max. beam size


SXT image overlaid with NoRH contours. (green/blue) NoRH 17/34GHz brightness temperatures in logarithmic scale. Field of View is the same as Partial Image above Contour levels are log10(Tb) = 5,6,7,8,...


HXT image overlaid with NoRH contours. (green/blue) NoRH 17/34GHz brightness temperatures in logarithmic scale. Field of View is the same as Partial Image above Contour levels are log10(Tb) = 5,6,7,8,...
