Moon surface feature - 6.5.2022 at 21.04 Kauhava Observation number 106659

Visibility IV / V

Jari Kankaanpää, Lakeuden Ursa

The double crater Boussingault in the eastern part of the South Pole is a good fixed point for orienteering in the area. It has a diameter of 131 kilometers. At the bottom of Helmholz, to the left of Boussingault, is a straight ridge like the hand of a bell. Thanks to the ligation, the re-embankment of the Hale Crater behind Boussingault can be seen, but the bottom is not. In the picture, the south is at the top. A strong wind disturbed the otherwise good weather.
