New Moon on . The illuminated surface of the Moon is 0%. Lunar cycle is 1 day young.
* The exact date and time of this New Moon phase is on 16 September 2031 at 18:47 UTC.
The moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.

Main moon phases of the following lunar cycle.
Moon is passing about ∠20° of ♍ Virgo tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2031 after 14 days on 30 September 2031 at 18:58.
There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.
Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1814" and ∠1909".
At 18:47 on this date the Moon completes the old and enters a new synodic month with lunation 392 of Meeus index or lunation 1345 from Brown series.
The length of the lunation is 29 days, 13 hours and 34 minutes. It is 45 minutes longer than the next 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 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 11 September 2031 at 11:54 in ♋ Cancer 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 27 September 2031 at 07:09 in ♒ Aquarius.
The Moon is 395 154 km (245 537 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 366 841 km (227 944 mi).
9 days after descending node on 6 September 2031 at 16:34 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 21 September 2031 at 02:24 in ♏ Scorpio.
7 days since the last northern standstill on 8 September 2031 at 23:27 in ♊ Gemini when the Moon has reached North declination of ∠20.623° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-20.501° at the point of next southern standstill on 23 September 2031 at 05:46 in ♐ Sagittarius.
22 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.
The Moon is in a New Moon geocentric conjunction with the Sun and thus forming Sun-Moon-Earth syzygy alignment.
