transient lunar phenomena

(tran -see-ĕnt, -zee-) (TLP) Short-lived changes in the appearance of lunar features, including reddish glows and obscurations of surface detail, that are triggered by lunar tides. They often occur within lunar craters and around the perimeters of basins. A carbon spectrum was obtained from a TLP in the crater Alphonsus.

That being said, Mobberley skilfully demolishes several of Patrick's legends: he made up the story of Lorna the fiancee, deluded himself about sightings of Transient Lunar Phenomena, and his claims about assisting NASA prior to the Moon landings were untrue.
The search for lunar changes continues, now gentrified under the catchall term transient lunar phenomena. Remarkably, some past reported changes do involve accurately documented observations of topographic appearances that only reoccur under specific illumination and libration conditions.
Section programmes relating to topographic study, transient lunar phenomena and occultations continue to be revised to accommodate new approaches, and the Director is grateful, as ever, to the coordinators of those programmes.

But the amateur lunar observer, now effectively disenfranchised from his traditional cartographic activities, instead turned his attention more to the observation of what became known as transient lunar phenomena, or TLPs.
If a new volcanic eruption occurred within Plato (as is often dreamed of by transient lunar phenomena observers), the fluid lavas would flow toward the northwest side of the crater floor.
Patrick also increased the Section's emphasis on the observation of transient lunar phenomena (TLPs), working in conjunction with professionals from America.
