Infrared Studies of the Lunar Terrain: The Background Moon
Observations have been made of the unlit limb of the Moon at infrared wavelengths, and detailed apparent temperature charts for the entire limb are presented. A number of thermal anomalies lying close to the limb have been discovered. Evidence is presented that there are sufficient large boulders near the lunar limb to invalidate temperatures determined at a single infrared wavelength during the night or at eclipse. The possibility that thermal anomalies are produced by local variations in the area density of boulders is discussed.
