Bid farewell to the harvest moon this week as it cruises through Gemini, the twins, for a close encounter with the star Pollux.
In the early hours of 20 September, the moon will be a beautiful waning crescent with 30% of its visible surface illuminated. As the week goes on, and the moon draws closer to the sun, the illuminated percentage will drop and the moon will rise later and later until it disappears into the morning twilight. It will then be reborn a few days later in the evening sky as a new moon.
