摘要

Fifty years ago, lunar cartographers James Greenacre and Edward Barr made the most well-documented observation of transient lunar phenomena (TLPs). A TLP is an unusual coloration, flash, obscuration, or other anomalous observations of the Moon. One of the earliest TLP reports was the 1787 observation by William Herschel of a fluctuating brightness at the crater Aristarchus, seen in earthshine. Herschel thought he had witnessed a volcanic eruption, but astronomers with more familiarity observing the Moon under various illumination conditions politely informed him that Aristarchus normally looked like that in earthshine.
