Differential IR flux scans at 22 microns have been made across the nighttime lunar surface over a range of phases before and after new moon. The differential chopping technique effectively cancels atmospheric emission in the beam path but records the flux difference between adjacent resolution elements on the lunar disk. The scans show that the brightness temperature gradient across the highlands after sunset is much greater than that across the western maria. The large gradients consistently disappear approximately 3.5 days after sunset. The postsunset enhancement could be due to surface roughness in the highlands or to a significant surface rock population with a mean size of approximately 0.5 m.
The galactic nucleus was mapped at 10 microns with a resolution of a few arc seconds. Four discrete sources were resolved superimposed on an extended background.
