Last Quarter on . The illuminated surface of the moon is 48% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 12 August 2001 at 07:53 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 ∠22° of ♉ Taurus tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2001 after 21 days on 2 September 2001 at 21:43.
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 1.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1858" and ∠1894".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 19 of Meeus index or 972 from Brown series.
The length of this lunation is 29 days, 7 hours and 11 minutes and it is 21 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2001. 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 5 hours and 33 minutes shorter than the mean synodic month length. It is 36 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 ∠342.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠358.1°.
6 days since point of apogee on 5 August 2001 at 21:05 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 19 August 2001 at 05:43 in ♌ Leo.
The Moon is 385 791 km (239 719 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 357 159 km (221 928 mi).
11 days after descending node on 1 August 2001 at 06:21 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 August 2001 at 17:05 in ♊ Gemini.
10 days since the last southern standstill on 1 August 2001 at 18:05 in ♑ Capricorn when the Moon has reached South declination of ∠-23.427° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠23.488° at the point of next northern standstill on 16 August 2001 at 03:52 in ♋ Cancer.
24 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 19 August 2001 at 02:55 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.
