Capuanus Domes 2019.12.06 The 60 km diameter crater Capuanus lies inthe southern margin of Palus Epidemiarum and contains three domes on itsinterior. Per the Lunar Domes Atlas GLR Group (see http://capuanusdomes.blogspot.com/)Ca1 is 7 km in diameter and 100 meters high with a slope of 1.63ᵒ. Ca2 is 9 kmin diameter and also 100 meters high with a slope of 1.27ᵒ. Ca3 is 5 km indiameter, 80 meters high and has a slope of 1.04ᵒ. Since they are constrained within a smallarea of the Moon, it might seem that the domes should be of similar propertiesand composition, however, their varying slopes hint that there are differencesin their composition and viscosities. Clementine data suggest differences aswell; Ca2 and Ca3 have low TiO2-content basalt,while Ca1has basalt with higher TiO2 content and lower aluminumcontent.

Other features on the imager include RimaHesiodus, which angles across the left central image. Mercator (47 km) andCampanus (48 km), with its floor in shadows, are visible on the upper centralimage. On the upper right of the image the ring of Kies (44 km) lies nearlycompletely flooded by the lava flows of Mare Nubium, accompanied by the domeKies π to the left of Kies. Another image of the Kies area will follow in the near future. The crater diameter data source was Atlas of the Moon by Antonín Rükl
