This is the single known example of a TLP photograph from a traditional telescopic source. Coming as it does in the center of the Lunar disk, near Sinus Medii, it is a strong support for Hoagland's assertion of a "Lunar Dome" over the region. Only a massive, highly reflective structure could account for such a flare. There are many TLP reports from over the years, with explanations varrying from suspended dust particles to just plain fabrication on the part of the observer. This image, however, indicates the reports are more than fiction, but rather another confirmation that there are large, "glass-like" objects reflecting light back to earth on a regular basis.
Clementine also found TLP's in it's travels around the Moon:

Sorry, Clem doesn't get any better than this.
