Waning Gibbous on . The illuminated surface of the moon is 98% and getting smaller. The lunar cycle is 16 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 ∠14° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the Full Moon before 1 day on 20 September 2051 at 10:11.
Next Full Moon is the Hunter Moon of October 2051 after 28 days on 19 October 2051 at 19:13.
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 ∠1970" and ∠1911".
The Moon is 16 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°.
Moon is at perigee at 12:20 about 12 days since last apogee on 9 September 2051 at 04:18 in ♏ Scorpio 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 6 October 2051 at 15:34 in ♎ Libra.
This perigee Moon is 358 920 km (223 023 mi) away from Earth. It is 3 588 km closer than the mean perigee distance, but it is still 11 436 km further than the closest perigee of 21st century.
12 days after ascending node on 8 September 2051 at 15:18 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 22 September 2051 at 03:59 in ♈ Aries.
7 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 4 days to face maximum declination of ∠18.704° at the point of next northern standstill on 26 September 2051 at 07:36 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 13 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.
