Waning Crescent on . The illuminated surface of the moon is 39% and getting smaller. The lunar cycle is 23 days old.
The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Main moon phases of the following lunar cycle.
Moon is passing about ∠21° of ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 1 day on 30 August 2021 at 07:13.
Next Full Moon is the Harvest Moon of September 2021 after 20 days on 20 September 2021 at 23:55.
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 7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1901".
The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 267 of Meeus index or 1220 from Brown series.
The length of this lunation is 29 days, 11 hours and 2 minutes and it is 48 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 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 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 ∠264.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠297.8°.
1 day since point of apogee on 30 August 2021 at 02:22 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 11 September 2021 at 10:05 in ♏ Scorpio.
The Moon is 404 487 km (251 337 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 368 464 km (228 953 mi).
1 day after ascending node on 30 August 2021 at 05:13 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 12 September 2021 at 16:35 in ♏ Scorpio.
12 days since the last southern standstill on 18 August 2021 at 22:24 in ♑ Capricorn when the Moon has reached South declination of ∠-25.761° the lunar orbit is extending northward over the next day to face maximum declination of ∠25.868° at the point of next northern standstill on 2 September 2021 at 00:23 in ♋ Cancer.
1 day since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 7 September 2021 at 00:52 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.
