First Quarter on . The illuminated surface of the moon is 48% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 14 August 2051 at 16:49 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 passing about ∠19° of ♏ Scorpio tropical zodiac sector.
Next Full Moon is the Sturgeon Moon of August 2051 after 7 days on 22 August 2051 at 01:35.
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 6.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1778" and ∠1894".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 638 of Meeus index or 1591 from Brown series.
The length of this lunation is 29 days, 13 hours and 28 minutes and it is 2 hours and 46 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 44 minutes longer than the mean synodic month length. It is 6 hours and 19 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 ∠104.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠137°.
2 days since point of apogee on 12 August 2051 at 11:22 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 24 August 2051 at 08:43 in ♈ Aries.
The Moon is 403 135 km (250 496 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 363 298 km (225 743 mi).
2 days after ascending node on 12 August 2051 at 11:44 in ♎ Libra 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 25 August 2051 at 20:56 in ♈ Aries.
11 days since the last northern standstill on 2 August 2051 at 19:38 in ♊ Gemini when the Moon has reached North declination of ∠19.057° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-18.946° at the point of next southern standstill on 17 August 2051 at 06:45 in ♐ Sagittarius.
2 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 22 August 2051 at 01:35 in ♒ Aquarius 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.
