A transient lunar phenomenon (TLP), or lunar transient phenomenon (LTP), is a short-lived light, color, or change in appearance on the lunar surface.
Claims of short-lived lunar phenomena go back at least 1,000 years, with some having been observed independently by multiple witnesses or reputable scientists. Nevertheless, the majority of transient lunar phenomenon reports are irreproducible and do not possess adequate control experiments that could be used to distinguish among alternative hypotheses to explain their origins. Thus, few reports concerning these phenomena are ever published in peer reviewed scientific journals, and the lunar scientific community rarely discusses these observations.
Most lunar scientists will acknowledge that transient events such as outgassing and impact cratering do occur over geologic time: the controversy lies in the frequency of such events.
The term was created by Patrick Moore during his co-authoring of NASA Technical Report R-277 Chronological Catalog of Reported Lunar Events, published in 1968.

“What a phenomenon it has beenscience fiction, space fictionexploding out of nowhere, unexpectedly of course, as always happens when the human mind is being forced to expand; this time starwards, galaxy-wise, and who knows where next.”

For human natures daily food;

Sang halfway through its little inborn tune.”
