Last Quarter on . The illuminated surface of the moon is 53% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 28 October 2021 at 20:05 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 first ∠1° of ♌ Leo tropical zodiac sector.
Next Full Moon is the Beaver Moon of November 2021 after 21 days on 19 November 2021 at 08:58.
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 6.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1805" and ∠1932".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 269 of Meeus index or 1222 from Brown series.
The length of this lunation is 29 days, 10 hours and 9 minutes and it is 19 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2021. 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 2 hours and 35 minutes shorter than the mean synodic month length. It is 3 hours and 34 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 ∠323.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠342.3°.
3 days since point of apogee on 24 October 2021 at 15:30 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 5 November 2021 at 22:23 in ♏ Scorpio.
The Moon is 397 160 km (246 784 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 358 845 km (222 976 mi).
5 days after ascending node on 23 October 2021 at 11:47 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 6 November 2021 at 03:38 in ♐ Sagittarius.
1 day since the last northern standstill on 26 October 2021 at 16:04 in ♋ Cancer when the Moon has reached North declination of ∠26.291° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-26.328° at the point of next southern standstill on 8 November 2021 at 16:27 in ♑ Capricorn.
5 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 4 November 2021 at 21:15 in ♏ Scorpio 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.
