The Moon’s current phase for today and tonight is a Waning Crescent phase. This phase is best viewed just before the sunrise in the western sky. In this phase the Moon’s illumination is growing smaller each day until the New Moon. During this part of the Moon cycle, the Moon is getting closer to the Sun as viewed from Earth and the night side of the Moon is facing the Earth with only a small edge of the Moon being illuminated. It can also be a great time to see the features of the Moon’s surface. Along the edge where the illuminated portion meets the dark side, the craters and mountains cast long shadows making them easier to observe with a telescope or binoculars.
