Waning Gibbous on . The illuminated surface of the moon is 96% and getting smaller. The lunar cycle is 16 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 ∠13° of ♍ Virgo tropical zodiac sector.
Previous main lunar phase is the Full Moon before 1 day on 7 February 2031 at 12:46.
Next Full Moon is the Worm Moon of March 2031 after 27 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 5.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1841" and ∠1945".
The Moon is 16 days old and navigating from the middle to the last 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 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 9 days until the Moon reaches the point of next perigee on 19 February 2031 at 00:35 in ♒ Aquarius.
The Moon is 389 351 km (241 931 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 364 745 km (226 642 mi).
8 days after descending node on 1 February 2031 at 09:25 in ♊ Gemini the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 February 2031 at 11:21 in ♐ Sagittarius.
6 days since the last northern standstill on 2 February 2031 at 12:52 in ♊ Gemini when the Moon has reached North declination of ∠21.745° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-21.615° at the point of next southern standstill on 16 February 2031 at 13:25 in ♐ Sagittarius.
21 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.
In 12 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.
