ZZ-ZZ-U-September-2013.jpgAnother "Meteor Strike"?170 visiteAny type of clustering in sightings would be significant because one would expect a rather random distribution across the surface of the moon. This has not been the case. During Moon-Blink, NASA discovered that almost a third of the known sightings at the time came from the Aristarchus crater. The first known sighting was on February 4th, 1821, by Captain Kater and several more were seen for the next 100 years. Many described the event as resembling a star appearing momentarily in the crater or a wall being illuminated (Armagh, Hanks).
The first notable modern observation of the event took place on October 13, 1959, when E.H. Rowe looked at the crater through his 36-inch telescope. He also saw the white flash, but unlike others, he also spotted a reddish glow that was at the perimeter of the white flash. It lasted a few seconds, then only the normal glow remained. Just over 4 years later, on October 29, 1963, James A, Greenacre and Edward Barr (both at Lowell Observatory) examined the crater. They too saw red, orange, and pink colors but did not secure any pictures. However, Greenacre was established as a well-respected lunar expert, so the findings had some weight to them. And a few days later, on November 1 and 2, 1963 Zdenek Kopal and Thomas Rackham see similar luminescence on the moon and were able to photograph them. These findings were published in Scientific American that year, and more and more sightings of the event were being recorded by others. Astronauts even got a first-hand view of this. During Apollo 11, NASA was told that a TLP was happening at that moment in the crater. They asked the Apollo 11 crew to look at the crater from their vantage point and found that indeed the general area seemed to glow (Seargent 14, Hanks).
The usual theories came into play with the crater to explain its glowing aspects, and it should be noted that Aristarchus has some interesting properties in and of itself that make the seemingly anomalous clustering make more sense. For starts, its albedo (reflectivity) is much higher than its surroundings. Also, it has a central peak in its center that is rather high, catching lots of sunlight and adding to the contrast of its surroundings. And it’s in a prime viewing spot, being easy to spot and also visually interesting to look at. All of these make it a prime location for seeing TLPs.

The_Moon-Aristarchus_Plateau.jpgAristarchus Plateau: the cradle of TLP's77 visiteCaption NASA:"Anchored in the vast lava flows of the Moon's Oceanus Procellarum lies the Aristarchus Plateau. The bright impact crater at the corner of the plateau is Aristarchus, a young crater 42 Km wide and 3 Km deep. Only slightly smaller, lava flooded Herodotus crater is above and to the left.
A valley (or rille) feature likely carved by rapidly flowing lava or a collapsed lava tunnel, Vallis Schroteri begins just to the right of Herodotus and winds across the plateau for about 160 Km, eventually turning toward the top of the picture.
Aristarchus Plateau itself is like a rectangular island about 200 km across, raised up to 2 kilometers or so above the smooth surface of the lunar Ocean of Storms.
Recorded from a backyard observatory in Buffalo, New York, the contrast of light-colored ejecta around Aristarchus with surrounding dark, smooth, lava flooded surfaces suggests more familiar snowy scenes of planet Earth".MareKromium
