5 day old moon 10th feb 2019
The terminator is bisecting (from North to south) Mares Frigoris, Serenatis and Tranquillitatis.
Crater Theophilus is prominant about 1/3rd of the way up the terminator heading North, identifiable by the prominant mountain at its centre.
The prominant crater just North of mid point, with a bright Western rim and dark shadow within is Maskelyne. Move West from here to just within the terminator line and you reach the location where Neil Armstrong took his 'One small step for man....' (50 years ago this July 21st).
Slightly East and North of Maskelyne, a point of uplands/ mountains intrude into mare Tranquillitatis. This is the site of the Apollo 17 landing on 11th december 1972 in the Taurus-Littrow Valley.
