BIRT
Directory - Section 54


BRIEF DESCRIPTION
The eastern part of Mare Nubium with many wrinkle ridges. Not far from the crater Birt is Rupes Recta, the "straight fault", the most remarkable fault on the Moon. When illuminated from the east it casts a wide shadow which is  clearly visible through even a small telescope. In the setting Sun it resembles a fine white line. Larger telescopes reveal a cleft Rima Birt between the craters Birt E (4.9x2.9 km/600 m) and Birt F (3.1 km/470 m). Refer to your copy of the Antonin Rukl lunar atlas chart, page 135.
