Jari Kankaanpää, Lakeuden Ursa

The bay of rainbows Sinus Iridum sometimes emerges from the terminator as the Jura Mountains bordering it shine in the morning sun. The perimeter shows the door handle against a black night.

The golden handle was now a bit half of what it could look like at best. The diameter of the iridium is 260km.
