Two for One
Originally published January 6, 2009
image by Patricio Dominguez, Madrid, Spain
Sinus Aestuum has a conspicuous and almost straight mare wrinkle ridge running SW-NE along its SE margin. This is widely commented on. What is less common is the photograph. However it is not just the internal ring but all the mare surface NW to the braid-like ridge that has subsided. Some radial and tangential structures may be traces of block tectonics. That suggest that the development of block tectonics after the Imbrium impact in the Montes Appeninus and beyond. In this sense the Rima Bode II and its continuation towards the NE margin of Sinus Aestuum southern Marco Polo, could be the margin of two of these blocks. The dark mantle material east of Sinus Aestuum could be explained as a result of the volcanism generated after such block-tectonics.

Technical Details
The image above is a composite of two images. The first was taken January 4 when Sinus Aestuum was near the terminador, the second was taken some months ago during an almost full Moon with a similar libration. The composite image shows details of both: long shadows showing the relief and the albedo. Near terminator image: January 4, 2009 22:30 UT. Celestron CGE 800, Camera DMK 31 AF 03.AS, Infrared filter (Astronomik IR Pro 742)
Full Moon image: August 20, 2008 01:30UT. Celestron C8 (1978) on HEQ5 Camera DMK 31 AF 03.AS, Infrared filter (Astronomik IR Pro 742)
