Last Quarter on . The illuminated surface of the moon is 45% and getting smaller. The lunar cycle is 22 days old.
* The exact date and time of this Last Quarter phase is on 9 December 2009 at 00:13 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 ∠24° of ♍ Virgo tropical zodiac sector.
Next Full Moon is the Cold Moon of December 2009 after 22 days on 31 December 2009 at 19:13.
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% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1942" and ∠1948".
The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 122 of Meeus index or 1075 from Brown series.
The length of this lunation is 29 days, 16 hours and 48 minutes and it is 2 hours and 21 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 4 minutes longer than the mean synodic month length. It is 2 hours and 59 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠99.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠135.6°.
4 days since point of perigee on 4 December 2009 at 14:12 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 20 December 2009 at 14:54 in ♒ Aquarius.
The Moon is 369 190 km (229 404 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 731 km (252 110 mi).
4 days after descending node on 5 December 2009 at 03:18 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 18 December 2009 at 16:41 in ♑ Capricorn.
6 days since the last northern standstill on 2 December 2009 at 23:37 in ♊ Gemini when the Moon has reached North declination of ∠25.772° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-25.769° at the point of next southern standstill on 16 December 2009 at 02:38 in ♐ Sagittarius.
18 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 7 days on 16 December 2009 at 12:02 in ♐ Sagittarius 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.
