[ noun ] the period between successive new moons (29.531 days)
Synonyms Used in print (Cornell H. Mayer, "Radio Emission of the Moon...)They deduced from their measurements that the radio_emission from the whole disk of the moon varied during a lunation in a roughly sinusoidal fashion ; that the amplitude of the variation was considerably less_than the amplitude of the variation in the infrared_emission as measured by Pettit and Nicholson ( 1930 ) and Pettit ( 1935 ) ; and that the maximum of the radio_emission came about 3 - 1 2 days after Full_Moon , which is again in contrast to the infrared_emission , which reaches its maximum at Full_Moon . The variation in the 3 - cm emission of the moon during a lunation is very_much less_than the variation in the 8.6 - mm emission , as would be expected from the explanation of Piddington and Minnett ( 1949 ) .
