This is a composite view derived from PJ25 images 13 & 16 & 19 in the methane band. Gerald Eichstädt processed the images and reprojected them as from a common viewpoint, exactly matching that of the colour composite. I have merged the three images and adjusted the intensities so as to enhance details. The small, very bright spots are convective clouds (thunderstorms) in the chaotic cyclonic regions. Surprisingly, the methane-bright North Polar Hood is not obvious, possibly because of the way the viewing angle varies across the globe. But the long linear bands in the ‘Bland Zone’, seen in the colour image, are also visible in the methane image, and in some sectors they make a sharp southern edge to the Polar Hood.
