On October 31, 2025, the moon phase is Waxing Gibbous, with 69% of the moon lit up, according to NASA's Daily Moon Observation.
Without visual aids, notable features visible tonight include the Mare Vaporum, Mare Imbrium, and Mare Serenitatis. With binoculars, the Endymion Crater, Posidonius Crater, and Mare Nectaris can be seen. Telescope owners can also observe the Rima Ariadaeus and the Apollo 14 and 15 landing spots.
The next full moon is expected on November, as the moon completes its 29.5-day orbit around Earth.
The phases we see are caused by the changing angles between the Sun, Moon, and Earth.
