The Moon and Jupiter were up in a clearing sky so sketching became a possibility. It has been a while since I have sketched barebones with copy paper and a number 2 pencil but that is what seemed right. Our atmosphere was interfering with a good look at Jupiter so I turned to the Moon, a target rich environment.
This sketch includes a region in southern Oceanus Procellarum adjacent to Mare Cognitum. Copernican era, bright crater Euclides formed the center feature along with the Riphaeus mountains. The ancient Raphaeus mountains are the rim remains of a large 225 km. crater mostly buried under dark lava today. Names included for the mountain arcs of Riphaeus were: the Urals; Boreus; Major; Minor and others that I learned some 50 years ago but those designations are officially gone. The soft landing sites of Surveyor 3 and Apollo 12 are just beyond the sketching region to the lower left.
Tomorrow morning at Moonrise this region will be on the terminator producing its best view of the month in my opinion. Domes and volcanic rises become visible under these low sun times.
For this sketch I used: white copy paper, a No 2 graphite pencil and a piece of tissue for blending. The sketch was photographed and cropped
