Waning Crescent on . The illuminated surface of the moon is 4% and getting smaller. The lunar cycle is 27 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 leaving the last ∠1° of ♍ Virgo tropical zodiac sector and will enter ♎ Libra later.
Previous main lunar phase is the Last Quarter before 6 days on 8 October 2031 at 10:50.
Next Full Moon is the Hunter Moon of October 2031 after 15 days on 30 October 2031 at 07:33.
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 5.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1823" and ∠1924".
The Moon is 27 days old and navigating from the second to the final part of the current synodic month. This is lunation 392 of Meeus index or 1345 from Brown series.
The length of this lunation is 29 days, 13 hours and 34 minutes and it is 45 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 50 minutes longer than the mean synodic month length. It is 6 hours and 13 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 ∠245.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠281.8°.
5 days since point of apogee on 9 October 2031 at 06:23 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 22 October 2031 at 20:06 in ♑ Capricorn.
The Moon is 393 241 km (244 349 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 370 022 km (229 921 mi).
10 days after descending node on 3 October 2031 at 22:04 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 18 October 2031 at 06:54 in ♏ Scorpio.
8 days since the last northern standstill on 6 October 2031 at 07:31 in ♊ Gemini when the Moon has reached North declination of ∠20.418° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-20.359° at the point of next southern standstill on 20 October 2031 at 11:06 in ♐ Sagittarius.
23 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.
In 1 day on 16 October 2031 at 08:21 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.
