Mare Orientale - 17.3.2022 at 21.10 - 17.3.2022 at 21.20 Vantaa, Pähkinärinne Observation number 105894

Visibility III / V

Paula Wirtanen, Ursa (Helsinki)

Full moon time. The main focus of the evening at that time was Einstein, but it was not worth wasting a great moonlight anyway and I got to admire more at the same time. The Orientale pool (Mare Orientale and its surroundings, including the Lacus Veris and Lacus Autumni lakes) is more visible. Now I couldn’t see all the way to the opposite shore, but the shadows helped to see the area a little more closely.

Lacus Veris (Spring Lake) is an outer, slightly annular formation around the Mare. It was more visible now than usual. The outer ring of the pool was not separated from the brightness of the Moon, nor was anything particularly good. What was special was the pale area visible in the Mare, apparently the summit of the surrounding mountains.

Seeing caused quite a ripple, it ranged from mediocre to evasive.
