Lacus Timoris

Lat: 38.8°S, Long: 27.3°W, Diam: 117 km, Depth: km, [/R%C3%BCkl%2063 Rükl: 63]

When the morning terminator runs at 24 degrees WEST, every dedicated telescopic observer of this part of the moon could see a curious Clair-Obscur phenomenon between Lacus Timoris and Epimenides. This Clair-Obscur phenomenon looks like an equilateral triangle made of three bright starlike dots.
At the same moment of the above mentioned Clair-Obscur phenomenon, the shadow spire of the small hill north of the bowl-shaped crater Darney runs all the way toward the crater Darney C west of Darney itself (which is a good indicator to look for the Clair-Obscur phenomenon at Lacus Timoris!).
One should also observe Promontorium Banat, which is already illuminated by the sun while the sunrise terminator is still eastward!
Sunrise terminator runs between Promontorium Laplace and Helicon.
