First Quarter on . The illuminated surface of the moon is 56% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 23 August 2099 at 00:01 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 ∠7° of ♐ Sagittarius tropical zodiac sector.
Next Full Moon is the Sturgeon Moon of August 2099 after 7 days on 30 August 2099 at 17:56.
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 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1906" and ∠1898".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 1232 of Meeus index or 2185 from Brown series.
The length of this lunation is 29 days, 7 hours and 56 minutes and it is 46 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 4 hours and 48 minutes shorter than the mean synodic month length. It is 1 hour and 21 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 ∠339.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠355.4°.
5 days since point of perigee on 17 August 2099 at 14:24 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 1 September 2099 at 19:45 in ♓ Pisces.
The Moon is 376 015 km (233 645 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 116 km (252 349 mi).
4 days after descending node on 18 August 2099 at 13:42 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 1 September 2099 at 08:09 in ♓ Pisces.
10 days since the last northern standstill on 12 August 2099 at 14:22 in ♊ Gemini when the Moon has reached North declination of ∠28.579° the lunar orbit is extending southward over the next day to face maximum declination of ∠-28.632° at the point of next southern standstill on 25 August 2099 at 05:13 in ♐ Sagittarius.
18 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 30 August 2099 at 17:56 in ♓ Pisces 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.
