Last Quarter on . The illuminated surface of the moon is 51% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 10 September 2039 at 13:45 UTC.
The moon rises at midnight and sets at noon. It is visible to the south in the morning.

Main moon phases of the following lunar cycle.
Moon is passing about ∠17° of ♊ Gemini tropical zodiac sector.
Next Full Moon is the Hunter Moon of October 2039 after 21 days on 2 October 2039 at 07:23.
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 7.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1906".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 490 of Meeus index or 1443 from Brown series.
The length of this lunation is 29 days, 11 hours and 32 minutes and it is 46 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 1 hour and 12 minutes shorter than the mean synodic month length. It is 4 hours and 57 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 ∠260.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠294.5°.
Moon is at apogee at 14:24 about 12 days since last perigee on 29 August 2039 at 03:16 in ♑ Capricorn the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 23 September 2039 at 02:18 in ♐ Sagittarius.
This apogee Moon is 404 110 km (251 102 mi) away from Earth. This is the year's closest apogee of 2039. It is 1 298 km further than the mean apogee distance, but it is still 59 km closer than the farthest apogee of 21st century.
Moon is in ascending node in ♊ Gemini at 13:18 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 24 September 2039 at 01:47 in ♐ Sagittarius.
11 days since the last southern standstill on 29 August 2039 at 14:11 in ♑ Capricorn when the Moon has reached South declination of ∠-24.880° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠24.993° at the point of next northern standstill on 12 September 2039 at 12:07 in ♋ Cancer.
At 13:18 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.
In 7 days on 18 September 2039 at 08:23 in ♍ Virgo 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.
