First Quarter on . The illuminated surface of the moon is 48% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 17 September 2075 at 15:25 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 about ∠23° of ♐ Sagittarius tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2075 after 6 days on 24 September 2075 at 10:31.
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 2.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1909".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 936 of Meeus index or 1889 from Brown series.
The length of this lunation is 29 days, 12 hours and 41 minutes and it is 49 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 3 minutes shorter than the mean synodic month length. It is 6 hours and 6 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 ∠251.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠287.7°.
12 days since point of apogee on 4 September 2075 at 19:44 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 20 September 2075 at 11:42 in ♒ Aquarius.
The Moon is 364 524 km (226 505 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 367 790 km (228 534 mi).
12 days after ascending node on 5 September 2075 at 03:09 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 18 September 2075 at 19:47 in ♑ Capricorn.
12 days since the last northern standstill on 5 September 2075 at 01:11 in ♋ Cancer when the Moon has reached North declination of ∠22.823° the lunar orbit is extending southward over the next day to face maximum declination of ∠-22.947° at the point of next southern standstill on 18 September 2075 at 20:04 in ♑ Capricorn.
12 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 24 September 2075 at 10:31 in ♈ Aries 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.
