Transient lunar phenomenon

832:, West Germany, had observed a bright glow on the lunar surface—the same sort of eerie luminescence that has intrigued Moon watchers for centuries. The report was passed on to Houston and thence to the astronauts. Neil Armstrong reported back: "Hey, Houston. I'm looking north up toward Aristarchus now, and I can't really tell at that distance whether I really am looking at Aristarchus, but there's an area there that is considerably more illuminated than the surrounding area. It just has – seems to have a slight amount of fluorescence to it as a crater can be seen, and the area around the crater is quite bright." 138:
which was below writhed, as it were, in anxiety, and, to put it in the words of those who reported it to me and saw it with their own eyes, the moon throbbed like a wounded snake. Afterwards it resumed its proper state. This phenomenon was repeated a dozen times or more, the flame assuming various twisting shapes at random and then returning to normal. Then after these transformations the moon from horn to horn, that is along its whole length, took on a blackish appearance.

Based on repeat observations, he further stated that "Linné can never be seen under any illumination as a crater of the normal type" and that "a local change has taken place". Today, Linné is visible as a normal young impact crater with a diameter of about 1.5 miles (2.4 km). 145:. However, more recent studies suggest that it appears very unlikely the 1178 event was related to the formation of Crater Giordano Bruno, or was even a true transient lunar phenomenon at all. The millions of tons of lunar debris ejected from an impact large enough to leave a 22-km-wide crater would have resulted in an unprecedentedly intense, week-long 1195:, these must be regarded with caution. As discussed above, an equally plausible hypothesis for some of these events is that they are caused by the terrestrial atmosphere. If an event were to be observed at two different places on Earth at the same time, this could be used as evidence against an atmospheric origin. 1089:
