Waxing Gibbous on . The illuminated surface of the moon is 99% and growing larger. The lunar cycle is 13 days young.
The moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Main moon phases of the following lunar cycle.
Moon is passing about ∠22° of ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the First Quarter before 6 days on 21 December 2031 at 00:00.
Next Full Moon is the Cold Moon of December 2031 after 1 day on 28 December 2031 at 17:33.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 8.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1794" and ∠1951".
The Moon is 13 days young and navigating from the first to the middle part of the current synodic month. This is lunation 395 of Meeus index or 1348 from Brown series.
The length of this lunation is 29 days, 11 hours and 1 minute and it is 43 minutes longer than the upcoming lunation's length. This is the year's shortest synodic month of 2031. 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 1 hour and 43 minutes shorter than the mean synodic month length. It is 4 hours and 26 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠334.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠351.6°.
11 days since point of perigee on 15 December 2031 at 21:31 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 4 days until the Moon reaches the point of next apogee on 31 December 2031 at 13:16 in ♌ Leo.
The Moon is 399 453 km (248 209 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 406 203 km (252 403 mi).
2 days after descending node on 24 December 2031 at 18:44 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 8 January 2032 at 08:58 in ♏ Scorpio.
At 07:41 the Moon is meeting its standstill point to reach North declination of ∠20.355°. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-20.298° at the point of next southern standstill in ♐ Sagittarius on 10 January 2032 at 16:49.
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 1 day on 28 December 2031 at 17:33 in ♋ Cancer the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
