First Quarter on . The illuminated surface of the moon is 64% and growing larger. The lunar cycle is 9 days young.
* The exact date and time of this First Quarter phase is on 6 September 2019 at 03:10 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is passing first ∠1° of ♑ Capricorn tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2019 after 6 days on 14 September 2019 at 04:33.
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 3.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1840" and ∠1904".
The Moon is 9 days young and navigating through the first part of the current synodic month. This is lunation 243 of Meeus index or 1196 from Brown series.
The length of this lunation is 29 days, 7 hours and 49 minutes and it is 1 hour and 23 minutes shorter than the upcoming 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 4 hours and 55 minutes shorter than the mean synodic month length. It is 1 hour and 14 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 ∠356.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠11.4°.
7 days since point of perigee on 30 August 2019 at 15:57 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 13 September 2019 at 13:32 in ♓ Pisces.
The Moon is 389 539 km (242 048 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 378 km (252 512 mi).
11 days after ascending node on 27 August 2019 at 01:50 in ♋ Cancer the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 8 September 2019 at 17:35 in ♑ Capricorn.
11 days since the last northern standstill on 26 August 2019 at 17:53 in ♋ Cancer when the Moon has reached North declination of ∠22.473° the lunar orbit is extending southward over the next day to face maximum declination of ∠-22.539° at the point of next southern standstill on 8 September 2019 at 09:39 in ♑ Capricorn.
11 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 14 September 2019 at 04:33 in ♓ Pisces the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
