Waning Gibbous on . The illuminated surface of the moon is 90% and getting smaller. The lunar cycle is 18 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is passing about ∠17° of ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the Full Moon before 3 days on 30 October 2031 at 07:33.
Next Full Moon is the Beaver Moon of November 2031 after 26 days on 28 November 2031 at 23:18.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunar disc appears visually 7.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1793" and ∠1934".
The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 393 of Meeus index or 1346 from Brown series.
The length of this lunation is 29 days, 12 hours and 49 minutes and it is 53 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 5 minutes longer than the mean synodic month length. It is 6 hours and 58 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠281.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠312.6°.
10 days since point of perigee on 22 October 2031 at 20:06 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 6 November 2031 at 02:45 in ♌ Leo.
The Moon is 399 683 km (248 352 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 404 522 km (251 358 mi).
2 days after descending node on 31 October 2031 at 06:09 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 14 November 2031 at 15:32 in ♏ Scorpio.
At 15:55 the Moon is meeting its standstill point to reach North declination of ∠20.333°. This is the year's northernmost lunar standstill of 2031. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-20.336° at the point of next southern standstill in ♐ Sagittarius on 16 November 2031 at 18:24.
15 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.
In 12 days on 14 November 2031 at 21:10 in ♏ Scorpio the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
