| Abstract: | High spatial resolution 8–14 μm images of Venus were obtained on March 6, 1974. The planet was at a phase angle of 112° with the morning terminator in view. Our 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 brightnes temperature variations of roughly 1–3°K. The images also confirm the difference between polar and equatorial limb darkening. Finally, we present evidence for a night-day asymmetry in the flux, with the brightness temperature greater by about 2°K on the sunlit side. |
