Abstract : Observations of Mercury at 3.3 mm were made on 35 days in 1967 and 82 days in 1968 to (1) search for dependence of the disk-average brightness temperature on hermocentric longitude and (2) provide constraints on the range of values of the thermal parameters of Mercury's epilith (subsurface layers).
