Waning Gibbous on . The illuminated surface of the moon is 66% and getting smaller. The lunar cycle is 20 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 ♎ Libra tropical zodiac sector.
Previous main lunar phase is the Full Moon before 5 days on 16 January 2071 at 02:35.
Next Full Moon is the Snow Moon of February 2071 after 24 days on 14 February 2071 at 13:33.
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 4.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1857" and ∠1950".
The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 878 of Meeus index or 1831 from Brown series.
The length of this lunation is 29 days, 19 hours and 1 minute and it is 1 hour and 44 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2071. 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 6 hours and 16 minutes longer than the mean synodic month length. It is 47 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠187.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠214.7°.
6 days since point of perigee on 15 January 2071 at 08:40 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 27 January 2071 at 21:04 in ♐ Sagittarius.
The Moon is 386 040 km (239 874 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 168 km (252 381 mi).
Moon is in ascending node in ♎ Libra at 06:04 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 14 days until Moon's next descending node later on 4 February 2071 at 20:30 in ♈ Aries.
7 days since the last northern standstill on 14 January 2071 at 05:41 in ♊ Gemini when the Moon has reached North declination of ∠18.487° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-18.432° at the point of next southern standstill on 27 January 2071 at 15:29 in ♐ Sagittarius.
At 06:04 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.
In 9 days on 31 January 2071 at 07:16 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.
