Last Quarter on . The illuminated surface of the moon is 57% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 29 July 2100 at 05:09 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 leaving the last ∠2° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.
Next Full Moon is the Sturgeon Moon of August 2100 after 22 days on 19 August 2100 at 21:29.
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 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1890".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 1243 of Meeus index or 2196 from Brown series.
The length of this lunation is 29 days, 10 hours and 55 minutes and it is 1 hour and 7 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 49 minutes shorter than the mean synodic month length. It is 4 hours and 20 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 ∠261° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠294.6°.
11 days since point of perigee on 16 July 2100 at 14:15 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 29 July 2100 at 04:16 in ♉ Taurus.
The Moon is 405 293 km (251 837 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 176 km (251 143 mi).
4 days after ascending node on 24 July 2100 at 11:05 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 7 August 2100 at 17:51 in ♍ Virgo.
9 days since the last southern standstill on 19 July 2100 at 03:02 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.246° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠28.293° at the point of next northern standstill on 2 August 2100 at 09:03 in ♊ Gemini.
4 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
In 8 days on 5 August 2100 at 23:02 in ♌ Leo 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.
