Between full and last quarter moon – late at night or in the early morning – you might catch the moon in its waning gibbous phase. It’ll appear less than full but more than half-lighted. A full moon rises just at sunset. A waning gibbous moon rises later at night, somewhere between your local sundown and midnight.
A waning gibbous moon can surprise you if you happen to be out late in the evening and you catch it rising eerily, some hours after sunset, glowing red like a misshapen full moon when it’s near the horizon.
A waning gibbous moon also initiates a rash of questions about seeing the moon during the day.
If it rises late at night, you know the waning gibbous moon must set after sunrise.
Yes, the moon is up in the daylight time for half of every month. We just don’t see it as often there because a daylight moon is so pale, and the sun is so bright; if the moon is close to the sun, bright sunlight will drown it from view. Watch for the daylight moon in the west in the days following full moon. You’ll see it in early morning, floating like a pale ghost against the blue sky.
