What is a waning gibbous moon?


Ilija Desic caught a waning gibbous moon with seagulls in Belgrade, Serbia.

Between full and last quarter moon, late at night or in the early morning, you may see the moon in its waning gibbous phase: less than full but more than half-lighted. A full moon rises just at sunset. A waning gibbous moon rises later at night and appears in the morning sky.

A waning gibbous moon can surprise you if you happen to be out late in the evening. It rises eerily some hours after sunset, glowing red like a full moon when it’s near the horizon.

Sometimes it looks like a misshapen clone of a full moon.

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.

In fact, in the few days after full moon, you’ll often see the waning gibbous moon in the west in early morning, floating against the pale blue sky.

Jenney Disimon caught this daytime moon – a waning gibbous moon, 94.7% illuminated – from Sabah, North Borneo.

He said: “Three quarters of an hour after sunrise the daytime waning gibbous moon was photographed descending towards the top of a flowering African tulip (Spathodia campanulta) tree on Murambi Heights.”
