Fredholm was also captured on Apollo 15's orbital ITEK-panoramic frame AS15-P-9249.
Research: Danny Caes
Fredholm's bright "dome"
The somewhat bulbous looking hill or "dome" to the north of Fredholm (between Macrobius and Proclus) looks deceptively "bright" and "cloudy" on pre-sunset photographs of Mare Crisium's western part, see Howard Eskildsen's LPOD May 2nd, 2013 and Alex Sanz's LPOD August 28th, 2013.
Detection of Fredholm's "bright cloudy dome": Danny Caes (is this a phenomenon which could be observed during each lunation, always before local sunset?).
