Last Quarter on . The illuminated surface of the moon is 55% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 4 February 2051 at 01:40 UTC.
The moon rises at midnight and sets at noon. It is visible to the south in the morning.

Main moon phases of the following lunar cycle.
Moon is passing about ∠8° of ♏ Scorpio tropical zodiac sector.
Next Full Moon is the Snow Moon of February 2051 after 22 days on 25 February 2051 at 14:53.
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 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1787" and ∠1946".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 631 of Meeus index or 1584 from Brown series.
The length of this lunation is 29 days, 11 hours and 43 minutes and it is 1 hour and 32 minutes longer than the upcoming lunation's length. 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 1 hour and 1 minute shorter than the mean synodic month length. It is 5 hours and 8 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 ∠313.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠334.7°.
2 days since point of apogee on 31 January 2051 at 19:46 in ♎ Libra 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 12 February 2051 at 18:54 in ♓ Pisces.
The Moon is 401 148 km (249 262 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 360 557 km (224 040 mi).
Moon is in ascending node in ♏ Scorpio at 07:49 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 16 February 2051 at 04:27 in ♉ Taurus.
11 days since the last northern standstill on 23 January 2051 at 08:46 in ♊ Gemini when the Moon has reached North declination of ∠19.697° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-19.572° at the point of next southern standstill on 6 February 2051 at 23:17 in ♐ Sagittarius.
At 07:49 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 7 days on 11 February 2051 at 06:41 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.
