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 11 August 2081 at 16:32 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 ∠17° of ♏ Scorpio tropical zodiac sector.
Next Full Moon is the Sturgeon Moon of August 2081 after 7 days on 19 August 2081 at 11:15.
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 1.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1917" and ∠1894".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1009 of Meeus index or 1962 from Brown series.
The length of this lunation is 29 days, 7 hours and 38 minutes and it is 44 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2081. 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 6 minutes shorter than the mean synodic month length. It is 1 hour and 3 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 ∠341.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠357.1°.
5 days since point of perigee on 6 August 2081 at 03:56 in ♌ Leo 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 21 August 2081 at 05:57 in ♓ Pisces.
The Moon is 373 969 km (232 374 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 148 km (252 369 mi).
4 days after descending node on 7 August 2081 at 04:49 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 21 August 2081 at 00:00 in ♓ Pisces.
9 days since the last northern standstill on 1 August 2081 at 22:18 in ♊ Gemini when the Moon has reached North declination of ∠28.454° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-28.500° at the point of next southern standstill on 14 August 2081 at 14:13 in ♐ Sagittarius.
17 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 19 August 2081 at 11:15 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.
