NEW 2016 Putative dome
Crozier H at southern edge of
Mare Fecunditatis - Moon
age 4.8 days « « Southwest of the concentric double crater Crozier H we have found a dome like structure with a summit pit and in the small crater at the east a very flat upwarding. « LRO image of the same region with a resolution of 125m/pxl. Click the thumbnail images to load higher resolution |

Putative dome Maskelyne A in the northeast Mare
Tranquilitatis - Moon age
5.1 days We noticed a putative dome between the craters Maskelyne A and Maskelyne F. It has a size of approximately 10 x 12 km at an height of about 80 meters. The LRO image with a resolution of 64 m/px shows some structures on the surface that may be vents. There is a similar structure in Mare Fecunditatis. |

Fracastorius Fr 1 in the
southern Mare Nectaris - Moon age 5.1
days Fracastorius (124 km) is a floor fractured crater with a steep slope of its northern crater wall (tilted Crater) to Mare Nectaris. The northern Wall is almost completely flooded by the marelava and only fragments are visible. To the west there is a great dome with a size of approximately 37 x 27 km with an oval Caldera. Its height is about 350 meters. The Dome belongs to Class D and was probably formed by several lava flows. It is similar to the significantly smaller domes Arago Alpha and Arago Beta. The LRO image with a resolution of 125 m/px clearly shows the Caldera. |
 |
Fracastorius Fr 1 in the
southern Mare Nectaris - Moon age 5.5
days Fr 1 is an extreme difficult object to be imaged. The left image was taken only 0.4 days after the upper picture and the dome is just hardly visible. However, the Caldera is still clearly visible. |
 |
Piccolomini Pi 1 -
Moon age 6.1 days Pi 1 lies west of the crater Piccolomini ( 85 km) on the inside of Rupes Altai. It is one of the few highland craters (another dome in the highlands is Mee 1). He is a B1 dome with a diameter of 14 km and a height of about 350 meters. |
 |
Beaumont L- a dark halo crater
(DHC) - Moon age 6.1 days
- Illumination 30% Beaumont L (4.2 km) is a typical dark halo crater. No volcanic structure, but a normal impact, which brought the dark marelava to the surface. The image also shows again the area of the ​​Fracastarius dome, which is no longer visible at this moon age. |
 |
Beaumont L- a dark halo crater (DHC) -
Moon age 7.1 days (39
%) Again the dark halo crater Beaumont L and a small DHC further to the north with a size of 2 km. The image is noteworthy because there are secondary craters in the bright ejecta south of the crater Rosse (11 km). The largest craters have a diameter of about 1 km. The ejecta comes from the Tycho impact. Beaumont L at a Moon age of 7.5 days (44 %) |

NEW 2016 Putative dome near
Airy B east of the large crater Albategnius -
Moon age 7.8
days « « Direct north of the crater Airy B we found two domelike structures both with summit pits (marked with A and B). The diameter of the small crater Airy O near structure A has a diameter of about 4.5km. « LRO image of the same region with a resolution of 64m/pxl.

Fracastorius Fr 1 in the
southern Mare Nectaris - Moon age 18.9 days -
Illumination 78% This image from the year 2014 shows the dome Fri 1 at waning moon at a lunar age of 18.9 days . Dome and summit caldera are clearly visible. |
 |
Piccolomini Pi 1 -
Moon age 20.5 days -
Illumination 65% This image of Piccolomini 1 dates from 2013 and shows the dome at waning moon. In this situation, the dome raises very plastic from from its surroundings. |
