Waning Crescent on . The illuminated surface of the moon is 10% and getting smaller. The lunar cycle is 26 days old.
The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Main moon phases of the following lunar cycle.
Moon is passing about ∠23° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 3 days on 16 January 2031 at 12:47.
Next Full Moon is the Snow Moon of February 2031 after 18 days on 7 February 2031 at 12:46.
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 1.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1950".
The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 383 of Meeus index or 1336 from Brown series.
The length of this lunation is 29 days, 10 hours and 59 minutes and it is 19 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 1 hour and 45 minutes shorter than the mean synodic month length. It is 4 hours and 24 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 ∠5.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠21.6°.
14 days since point of apogee on 6 January 2031 at 11:00 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 21 January 2031 at 21:41 in ♑ Capricorn.
The Moon is 363 335 km (225 766 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 359 637 km (223 468 mi).
1 day after ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 1 February 2031 at 09:25 in ♊ Gemini.
At 05:10 the Moon is meeting its standstill point to reach South declination of ∠-21.824°. This is the year's southernmost lunar standstill of 2031. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠21.745° at the point of next northern standstill in ♊ Gemini on 2 February 2031 at 12:52.
1 day since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.
In 2 days on 23 January 2031 at 04:31 in ♒ Aquarius 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.
