Infrared imaging of Venus - 8-14 micrometers

High-spatial-resolution images of Venus were obtained at wavelengths between 8 and 14 microns when the planet was at a phase angle of 112 deg with the morning terminator in view. The images confirm the existence of a previously mapped flux anomaly near the south pole and show evidence of other infra...

The images confirm the existence of a previously mapped flux anomaly near the south pole and show evidence of other infrared features, presumably transient in nature. Flux differences of 2-7% were measured, corresponding to brightness temperature variations of roughly 1-3 K. The images also confirm the difference between polar and equatorial limb darkening. Finally, evidence is presented for a night-day asymmetry in the flux, with the brightness temperature greater by about 2 K on the sunlit side.
