Last Quarter on . The illuminated surface of the moon is 46% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 1 October 2010 at 03:52 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 ∠12° of ♋ Cancer tropical zodiac sector.
Next Full Moon is the Hunter Moon of October 2010 after 21 days on 23 October 2010 at 01:36.
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 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1925" and ∠1917".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 132 of Meeus index or 1085 from Brown series.
The length of this lunation is 29 days, 8 hours and 15 minutes and it is 1 hour and 52 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 4 hours and 29 minutes shorter than the mean synodic month length. It is 1 hour and 40 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 ∠4.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠20.4°.
10 days since point of apogee on 21 September 2010 at 08:03 in ♓ Pisces 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 6 October 2010 at 13:41 in ♍ Virgo.
The Moon is 372 272 km (231 319 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 359 453 km (223 354 mi).
Moon is in descending node in ♋ Cancer at 02:42 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 12 days until Moon's next ascending node later on 13 October 2010 at 15:36 in ♐ Sagittarius.
1 day since the last northern standstill on 29 September 2010 at 17:37 in ♊ Gemini when the Moon has reached North declination of ∠24.555° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-24.457° at the point of next southern standstill on 12 October 2010 at 07:49 in ♐ Sagittarius.
14 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 7 October 2010 at 18:44 in ♎ Libra 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.
