Additional Information

Clair-Obscur phenomenon (equilateral triangle of three starlike dots)

  • 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. It was discovered several years ago by Danny Caes while looking through the restored Cooke-Steinheil refractor of the Public Observatory in Ghent - Belgium (Van Monckhoven observatory).
