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 21 August 2017 at 18:30 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 ∠25° of ♌ Leo tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2017 after 15 days on 6 September 2017 at 07:03.
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 ∠1915" and ∠1897".
At 18:30 on this date the Moon completes the old and enters a new synodic month with lunation 218 of Meeus index or lunation 1171 from Brown series.
The length of the lunation is 29 days, 11 hours and 1 minute. It is 2 hours and 42 minutes shorter than the next 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 1 hour and 44 minutes shorter than the mean synodic month length. It is 4 hours and 25 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit is ∠49.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠79°.
2 days since point of perigee on 18 August 2017 at 13:14 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next apogee on 30 August 2017 at 11:25 in ♐ Sagittarius.
The Moon is 374 298 km (232 578 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 404 307 km (251 225 mi).
Moon is in ascending node in ♌ Leo at 10:34 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 14 days until Moon's next descending node later on 4 September 2017 at 18:41 in ♒ Aquarius.
3 days since the last northern standstill on 18 August 2017 at 06:50 in ♋ Cancer when the Moon has reached North declination of ∠19.381° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-19.393° at the point of next southern standstill on 1 September 2017 at 02:03 in ♑ Capricorn.
At 10:34 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.
The Moon is in a New Moon geocentric conjunction with the Sun and thus forming Sun-Moon-Earth syzygy alignment.
