Waning Crescent on . The illuminated surface of the moon is 33% and getting smaller. The lunar cycle is 23 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 ∠18° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 1 day on 14 February 2031 at 22:50.
Next Full Moon is the Worm Moon of March 2031 after 20 days on 9 March 2031 at 04:30.
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 1.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1942".
The Moon is 23 days old and navigating from the second to the final 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°.
13 days since point of apogee on 2 February 2031 at 23:45 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 19 February 2031 at 00:35 in ♒ Aquarius.
The Moon is 363 692 km (225 988 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 364 745 km (226 642 mi).
1 day after ascending node on 15 February 2031 at 11:21 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 28 February 2031 at 11:02 in ♊ Gemini.
At 13:25 the Moon is meeting its standstill point to reach South declination of ∠-21.615°. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠21.491° at the point of next northern standstill in ♊ Gemini on 1 March 2031 at 20:54.
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 5 days on 21 February 2031 at 15:49 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.
