Waning Gibbous on . The illuminated surface of the moon is 90% 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 ∠10° of ♓ Pisces tropical zodiac sector.
Previous main lunar phase is the Full Moon before 2 days on 23 July 2051 at 16:36.
Next Full Moon is the Sturgeon Moon of August 2051 after 26 days on 22 August 2051 at 01:35.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1947" and ∠1889".
The Moon is 17 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°.
10 days since point of apogee on 15 July 2051 at 16:49 in ♎ Libra the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 28 July 2051 at 00:46 in ♈ Aries.
The Moon is 368 101 km (228 727 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 368 220 km (228 801 mi).
10 days after ascending node on 16 July 2051 at 09:35 in ♎ Libra the Moon is positioned north of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from North to South in descending node on 29 July 2051 at 18:33 in ♈ Aries.
5 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 7 days to face maximum declination of ∠19.057° at the point of next northern standstill on 2 August 2051 at 19:38 in ♊ Gemini.
10 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 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.
