Montes Caucasus - 28.9.2021 at 03.10 - 28.9.2021 at 04.00 Harjavalta Observation number 101590

Visibility IV / V

Jari Kuula, Porin Karhunvartijat

The company draws the Caucasus Mountains in its evening light. Calippus C has lost its western edge, but the eastern edge, especially its southern part, rises to a height of 5 km. Montes Caucasus is said to be an Imbrium throw, but the concentric alignments don't really fit !? A cell phone rap at 3:49 a.m. shows a low ridge heading northeast from Theaetus. This shallow form has a width of about 25 km and a length of about 100 km. The ridge did not appear in the drawing, but the shoreline is also in the shade.
