Waning Gibbous on . The illuminated surface of the moon is 67% and getting smaller. The lunar cycle is 20 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 ∠12° of ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the Full Moon before 5 days on 20 September 2051 at 10:11.
Next Full Moon is the Hunter Moon of October 2051 after 24 days on 19 October 2051 at 19:13.
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% wider than solar disc. Moon and Sun apparent angular diameters are ∠1944" and ∠1914".
The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 639 of Meeus index or 1592 from Brown series.
The length of this lunation is 29 days, 16 hours and 14 minutes and it is 1 hour and 58 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 3 hours and 29 minutes longer than the mean synodic month length. It is 3 hours and 33 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 ∠137° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠163.9°.
3 days since point of perigee on 21 September 2051 at 12:20 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 11 days until the Moon reaches the point of next apogee on 6 October 2051 at 15:34 in ♎ Libra.
The Moon is 368 646 km (229 066 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 406 415 km (252 535 mi).
3 days after descending node on 22 September 2051 at 03:59 in ♈ Aries the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 5 October 2051 at 20:55 in ♎ Libra.
11 days since the last southern standstill on 13 September 2051 at 15:30 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.758° the lunar orbit is extending northward over the next day to face maximum declination of ∠18.704° at the point of next northern standstill on 26 September 2051 at 07:36 in ♊ Gemini.
16 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.
In 9 days on 4 October 2051 at 20:47 in ♎ Libra 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.
