• Arago Beta was very vaguely captured on Lunar Orbiter IV's photograph LOIV-85-H1. See the upper left corner of the Hi-Res scan of that photograph.- DannyCaes DannyCaes May 2, 2010

Description

Description: Elger

([/IAU%20Directions IAU Directions]) There are two curious circular protuberances on the Mare W. of [/Arago Arago], which are well seen when the E. longitude of the morning terminator is about 19 deg., and a long cleft, passing about midway between them, and extending from the foot of the W. wall to a small crater on the edge of the Mare near [/Sosigenes Sosigenes].

Additional Information

• The positions of the domes listed in the title lines are based on [/LTVT LTVT] measurements of an Earth-based photo by Paolo Lazzarotti registered to the 1994 [/ULCN ULCN]. The height estimates are from the most recent [/GLR GLR] Lunar Dome Catalog (see below). The shadow cast by Arago Alpha in [/Consolidated%20Lunar%20Atlas Consolidated Lunar Atlas] plate D5 gives a height of ~300 m, in reasonable agreement with the GLR value. - JimMosher JimMosher
• In his 1964 Dome Catalog, Brungart listed Arago Alpha as "Arago 2", assigning it an "order of magnitude" height of 700 m, and listed Arago Beta as "Arago 1", assigning it a height of 800 m
• The [/domes 2005 GLR Lunar Dome Catalog] agrees with the title line on the diameters, but gives the heights of Arago Alpha and Beta (which, like Brungart, it lists as Arago 2 and 1) as 150 m and 800 m, respectively. This appears to be an underestimate for Alpha and a considerable overestimate for Beta. The origin of the 150 m height for Arago Alpha is unclear.
• A 2005 article by Lena et al. (see Bibliography, below), appearing simultaneously with the announcement of the 2005 GLR Lunar Dome Catalog, gives height estimates based on shape-from-shading/photoinclinometry of 330+/-30 m and 270+/-30 m.
• These numbers are repeated in the 2006 Icarus article by the same group (see below), where the features are assigned the new names "A2" (Arago Alpha) and "A3" (Arago Beta).
• The current GLR Consolidated Lunar Dome Catalogue reproduces the information from the Icarus article, giving the heights as 330 m (A2 = Arago Alpha) and 270 m (A3 = Arago Beta).
• North-northwest of the large dome Arago Alpha is (or should be) the impact location of Ranger 6, which was an unsuccessful attempt to make close-up photographs of the moon while the probe descended toward the lunar surface.
  The exact coordinates of Ranger 6's impact location are: 9°24' North/ 21°30' East.
  Note that chart 35 of Antonin Rukl's Atlas of the Moon doesn't show the location of Ranger 6.
