First Quarter on . The illuminated surface of the moon is 50% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 19 January 2051 at 12:38 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠1° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.
Next Full Moon is the Wolf Moon of January 2051 after 7 days on 26 January 2051 at 21:20.
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 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1961" and ∠1950".
The Moon is 7 days young and navigating through the first 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°.
3 days since point of perigee on 15 January 2051 at 18:23 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 12 days until the Moon reaches the point of next apogee on 31 January 2051 at 19:46 in ♎ Libra.
The Moon is 365 530 km (227 130 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 405 173 km (251 763 mi).
12 days after ascending node on 7 January 2051 at 05:43 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 20 January 2051 at 03:36 in ♉ Taurus.
8 days since the last southern standstill on 10 January 2051 at 12:25 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.761° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠19.697° at the point of next northern standstill on 23 January 2051 at 08:46 in ♊ Gemini.
12 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 26 January 2051 at 21:20 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.
