Subtle variations in the opacities are revealed in this color composite generated from mapped 1.74-µm (red), 2.26-µm (green) and 2.32-µm (blue) images taken on September 27, 2016, at 11:02:09, 11:03:31 and 11:11:19 UT, respectively. The image scale is 0.1°/pixel in latitude and longitude. The images have not been corrected for any limb darkening but are calibrated. The color variations illustrate the variation of opacities at the wavelengths arising from trace species and aerosol abundances
