First Quarter on . The illuminated surface of the moon is 53% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 16 September 2086 at 05:17 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 ∠3° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.
Next Full Moon is the Harvest Moon of September 2086 after 6 days on 23 September 2086 at 01:15.
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 3.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1846" and ∠1909".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 1072 of Meeus index or 2025 from Brown series.
The length of this lunation is 29 days, 16 hours and 39 minutes and it is 1 hour and 18 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 3 hours and 55 minutes longer than the mean synodic month length. It is 3 hours and 8 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 ∠157.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠181.4°.
6 days since point of apogee on 10 September 2086 at 10:10 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 23 September 2086 at 10:35 in ♈ Aries.
The Moon is 388 238 km (241 240 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 357 038 km (221 853 mi).
1 day after ascending node on 14 September 2086 at 21:12 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 27 September 2086 at 11:17 in ♊ Gemini.
1 day since the last southern standstill on 15 September 2086 at 19:03 in ♐ Sagittarius when the Moon has reached South declination of ∠-21.940° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠21.839° at the point of next northern standstill on 28 September 2086 at 08:31 in ♊ Gemini.
1 day since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 23 September 2086 at 01:15 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.
