Last Quarter on . The illuminated surface of the moon is 42% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 10 September 2001 at 19:00 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 ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.
Next Full Moon is the Hunter Moon of October 2001 after 21 days on 2 October 2001 at 13:49.
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 0.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1915" and ∠1906".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 20 of Meeus index or 973 from Brown series.
The length of this lunation is 29 days, 7 hours and 32 minutes and it is 1 hour and 24 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 5 hours and 12 minutes shorter than the mean synodic month length. It is 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 ∠358.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠13.2°.
9 days since point of apogee on 1 September 2001 at 23:26 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 16 September 2001 at 15:50 in ♍ Virgo.
The Moon is 374 215 km (232 526 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 128 km (222 530 mi).
Moon is in ascending node in ♊ Gemini at 21:36 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 24 September 2001 at 10:28 in ♑ Capricorn.
13 days since the last southern standstill on 28 August 2001 at 23:14 in ♑ Capricorn when the Moon has reached South declination of ∠-23.546° the lunar orbit is extending northward over the next day to face maximum declination of ∠23.677° at the point of next northern standstill on 12 September 2001 at 12:19 in ♋ Cancer.
At 21:36 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 5 days on 17 September 2001 at 10:27 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.
