Waning Gibbous on . The illuminated surface of the moon is 97% 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 ∠17° of ♓ Pisces tropical zodiac sector.
Previous main lunar phase is the Full Moon before 1 day on 19 August 2100 at 21:29.
Next Full Moon is the Harvest Moon of September 2100 after 27 days on 18 September 2100 at 11:32.
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 4.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1805" and ∠1897".
The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1244 of Meeus index or 2197 from Brown series.
The length of this lunation is 29 days, 9 hours and 48 minutes and it is 35 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 2 hours and 56 minutes shorter than the mean synodic month length. It is 3 hours and 13 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 ∠294.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠320.8°.
10 days since point of perigee on 10 August 2100 at 16:07 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next apogee on 25 August 2100 at 23:00 in ♉ Taurus.
The Moon is 397 031 km (246 704 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 404 637 km (251 430 mi).
1 day after ascending node on 20 August 2100 at 18:39 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 4 September 2100 at 02:42 in ♍ Virgo.
6 days since the last southern standstill on 15 August 2100 at 09:13 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.334° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠28.356° at the point of next northern standstill on 29 August 2100 at 17:37 in ♊ Gemini.
1 day since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
In 13 days on 4 September 2100 at 08:49 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.
