Waxing Crescent on . The illuminated surface of the moon is 32% and growing larger. The lunar cycle is 6 days young.
The moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Main moon phases of the following lunar cycle.
Moon is passing about ∠17° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the New Moon before 5 days on 23 January 2031 at 04:31.
Next Full Moon is the Snow Moon of February 2031 after 10 days on 7 February 2031 at 12:46.
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 5.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1837" and ∠1948".
The Moon is 6 days young and navigating from the beginning to the first part of the current synodic month. This is lunation 384 of Meeus index or 1337 from Brown series.
The length of this lunation is 29 days, 11 hours and 18 minutes and it is 42 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 26 minutes shorter than the mean synodic month length. It is 4 hours and 43 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 ∠21.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠41.9°.
6 days since point of perigee on 21 January 2031 at 21:41 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 5 days until the Moon reaches the point of next apogee on 2 February 2031 at 23:45 in ♊ Gemini.
The Moon is 390 212 km (242 466 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 405 416 km (251 914 mi).
9 days after ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 1 February 2031 at 09:25 in ♊ Gemini.
8 days since the last southern standstill on 20 January 2031 at 05:10 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.824° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠21.745° at the point of next northern standstill on 2 February 2031 at 12:52 in ♊ Gemini.
9 days 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 10 days on 7 February 2031 at 12:46 in ♌ Leo 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.
