First Quarter on . The illuminated surface of the moon is 52% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 28 August 2066 at 08:25 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 Harvest Moon of September 2066 after 6 days on 4 September 2066 at 01:37.
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% wider than solar disc. Moon and Sun apparent angular diameters are ∠1961" and ∠1900".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 824 of Meeus index or 1777 from Brown series.
The length of this lunation is 29 days, 12 hours and 58 minutes and it is 1 hour and 3 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 13 minutes longer than the mean synodic month length. It is 6 hours and 49 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 ∠236.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠272.1°.
12 days since point of apogee on 16 August 2066 at 05:19 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 1 September 2066 at 01:49 in ♑ Capricorn.
The Moon is 365 474 km (227 095 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 365 541 km (227 137 mi).
11 days after descending node on 16 August 2066 at 21:14 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 30 August 2066 at 14:05 in ♐ Sagittarius.
13 days since the last northern standstill on 15 August 2066 at 06:35 in ♊ Gemini when the Moon has reached North declination of ∠24.625° the lunar orbit is extending southward over the next day to face maximum declination of ∠-24.516° at the point of next southern standstill on 29 August 2066 at 07:59 in ♐ Sagittarius.
25 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 4 September 2066 at 01:37 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.
