Waning Gibbous on . The illuminated surface of the moon is 92% and getting smaller. The lunar cycle is 17 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is passing about ∠5° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the Full Moon before 2 days on 22 August 2051 at 01:35.
Next Full Moon is the Harvest Moon of September 2051 after 26 days on 20 September 2051 at 10:11.
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 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1898".
The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 638 of Meeus index or 1591 from Brown series.
The length of this lunation is 29 days, 13 hours and 28 minutes and it is 2 hours and 46 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 44 minutes longer than the mean synodic month length. It is 6 hours and 19 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 ∠104.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠137°.
Moon is at perigee at 08:43 about 11 days since last apogee on 12 August 2051 at 11:22 in ♎ Libra the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 15 days until point of next apogee on 9 September 2051 at 04:18 in ♏ Scorpio.
This perigee Moon is 363 298 km (225 743 mi) away from Earth. It is 790 km closer than the mean perigee distance, but it is still 7 058 km further than the closest perigee of 21st century.
12 days after ascending node on 12 August 2051 at 11:44 in ♎ Libra the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 25 August 2051 at 20:56 in ♈ Aries.
7 days since the last southern standstill on 17 August 2051 at 06:45 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.946° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠18.858° at the point of next northern standstill on 30 August 2051 at 01:37 in ♊ Gemini.
12 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the beginning to the first part of the lunar cycle.
In 11 days on 5 September 2051 at 04:33 in ♍ Virgo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
