The Moon is moving through the stars of Capricornus and there’s a good opportunity to see Earthshine on the waning crescent this morning. Observers in the southern hemisphere get an added bonus – Mercury is an easy target above the eastern horizon. It passes close to Neptune today but the distant world may be too faint to see in the early morning twilight.
