Waxing Crescent on . The illuminated surface of the moon is 18% and growing larger. The lunar cycle is 4 days young.
The moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Main moon phases of the following lunar cycle.
Moon is passing about ∠19° of ♎ Libra tropical zodiac sector.
Previous main lunar phase is the New Moon before 4 days on 18 August 2031 at 04:32.
Next Full Moon is the Harvest Moon of September 2031 after 9 days on 1 September 2031 at 09:20.
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 1.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1866" and ∠1897".
The Moon is 4 days young and navigating from the beginning to the first part of the current synodic month. This is lunation 391 of Meeus index or 1344 from Brown series.
The length of this lunation is 29 days, 14 hours and 15 minutes and it is 41 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 1 hour and 31 minutes longer than the mean synodic month length. It is 5 hours and 32 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 ∠213.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠245.2°.
7 days since point of apogee on 14 August 2031 at 21:37 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 30 August 2031 at 12:53 in ♒ Aquarius.
The Moon is 384 059 km (238 643 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 361 684 km (224 740 mi).
11 days after descending node on 10 August 2031 at 14:10 in ♉ Taurus 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 25 August 2031 at 01:21 in ♏ Scorpio.
9 days since the last northern standstill on 12 August 2031 at 15:58 in ♊ Gemini when the Moon has reached North declination of ∠20.868° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-20.731° at the point of next southern standstill on 26 August 2031 at 23:55 in ♐ Sagittarius.
24 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.
In 9 days on 1 September 2031 at 09:20 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.
