Waning Gibbous on . The illuminated surface of the moon is 61% and getting smaller. The lunar cycle is 21 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 ∠23° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the Full Moon before 5 days on 23 July 2051 at 16:36.
Next Full Moon is the Sturgeon Moon of August 2051 after 23 days on 22 August 2051 at 01:35.
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 4.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1890".
The Moon is 21 days old and navigating from the middle to the last part of the current synodic month. This is lunation 637 of Meeus index or 1590 from Brown series.
The length of this lunation is 29 days, 10 hours and 56 minutes and it is 2 hours and 32 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 1 hour and 48 minutes shorter than the mean synodic month length. It is 4 hours 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 ∠70.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠104.1°.
1 day since point of perigee on 28 July 2051 at 00:46 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 12 August 2051 at 11:22 in ♎ Libra.
The Moon is 363 301 km (225 745 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 404 639 km (251 431 mi).
Moon is in descending node in ♈ Aries at 18:33 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 13 days until Moon's next ascending node later on 12 August 2051 at 11:44 in ♎ Libra.
8 days since the last southern standstill on 20 July 2051 at 20:52 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.133° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠19.057° at the point of next northern standstill on 2 August 2051 at 19:38 in ♊ Gemini.
13 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the middle to the last part of the lunar cycle.
In 8 days on 6 August 2051 at 15:05 in ♌ Leo 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.
