First Quarter on . The illuminated surface of the moon is 55% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 13 October 2051 at 00:12 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 ∠4° of ♑ Capricorn tropical zodiac sector and will enter ♒ Aquarius later.
Next Full Moon is the Hunter Moon of October 2051 after 6 days on 19 October 2051 at 19:13.
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 3.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1864" and ∠1923".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 640 of Meeus index or 1593 from Brown series.
The length of this lunation is 29 days, 18 hours and 12 minutes and it is 26 minutes shorter 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 5 hours and 28 minutes longer than the mean synodic month length. It is 1 hour and 35 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 ∠163.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠187.8°.
6 days since point of apogee on 6 October 2051 at 15:34 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 19 October 2051 at 22:41 in ♈ Aries.
The Moon is 384 619 km (238 991 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 356 809 km (221 711 mi).
7 days after ascending node on 5 October 2051 at 20:55 in ♎ Libra the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 19 October 2051 at 14:46 in ♈ Aries.
2 days since the last southern standstill on 10 October 2051 at 22:36 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.669° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠18.671° at the point of next northern standstill on 23 October 2051 at 15:33 in ♊ Gemini.
7 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 6 days on 19 October 2051 at 19:13 in ♈ Aries 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.
