Wildey, Robert L. Abstract The 8-14 ~ infrared emission of Jupiter has been observed on six nights in December of 1963 using the 200-in. Hale telescope. The new observations possess twice the resolution of those obtained in 1962. The brightness temperature at the center of the disk appears to be closely constant at 1290K. With some slight ambiguity, the light bands are about 0?5 cooler in appearance than the dark bands. There is some suggestion of morning-evening asymmetry in one of the bands. The Great Red Spot is found to be from 1?5 to 2?0 cooler than the surrounding disk at the newer resolution. The observations were collected with a photometer employing a mercury-doped germanium photoconductor utilized as a 180 cps transducer through the use of a simple articulated double mirror spatial filter which eliminates a large portion of sky-telescope background from the signal. The present limitations to these maps arise from the nonstationary nature of part of the noise. In the future, noise-suppressed maps may be possible without superposition of several maps, which may then remove some of the ambiguity of the present interpretation. These observations will be presented in greater detail in the current issue of the Journal of Geophysical Research.
