Paper, we compare the spatial distribution of robust tlp sites to transient outgassing (seen by apollo and lunar prospector instruments) to a high conﬁdence, robust tlp sites and those of lunar outgassing correlate strongly, further arguing for the reality of tlps key words: catalogs – methods: statistical – moon online-only material: color ﬁgure 1. Transient lunar phenomena (tlp) this last category may include volcanic activity and / or outgassing of some sort tlps have been observed on the moon since 1540, perhaps as far back as 1178.
But sometimes you can hit a very stubborn (metaphorical) brick wall and we can be left completely stumped by the strangeness of an event or occurrence and this definitely true of the very baffling transient lunar phenomenon (tlp. Introduction: with recent interest in transient lunar phenomena (tlp) and lunar out-gassing theories [1-3], the tlp catalogs of middlehurst  and came- maining tlp reports are used in this analysis spectively either side of the sub results: however there is.
2 transient lunar phenomena tlps as observed are apparently rare events, and therefore the tlp database is largely anecdotal furthermore, since tlps are observed for short durations, there is rarely the op-portunity to accomplish possibly corroborating observations, such as photography or spec-troscopy. Reports of transient lunar phenomena range from foggy patches to permanent changes of the lunar landscape cameron  classifies these as (1) gaseous, involving mists and other forms of obscuration, (2) reddish colorations, (3) green, blue or violet colorations, (4) brightenings, and (5) darkening.
Introduction transient lunar phenomena (tlp) is a term used to describe anything which is seen on the moon which is not supposed to be there, and which contradicts the view that the surface of the moon is dead and unchanging.
Literature and received reports of lunar transient phenomena (ltp) in lunar programs of observations provided a collection of 2254 total of observations, from 557-1994 ad with sufficient information for auxiliary data analysis.
