Crescent ♎ Libra
Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 45% and getting smaller. The 22 days old Moon is in ♎ Libra.
* The exact date and time of this Last Quarter phase is on 18 December 2011 at 00:48 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing first ∠2° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1961" and ∠1950".
Next Full Moon is the Wolf Moon of January 2012 after 21 days on 9 January 2012 at 07:30.
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.
The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 147 of Meeus index or 1100 from Brown series.
The length of the lunation is 29 days, 11 hours and 57 minutes. It is 1 hour and 36 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 47 minutes shorter than the mean synodic month length. It is 5 hours and 22 minutes longer compared to 21st century's shortest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠21.6°. At the beginning of next synodic month the true anomaly is going to be ∠42.1°.
12 days after point of apogee on 6 December 2011 at 01:13 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next perigee on 22 December 2011 at 02:56 in ♏ Scorpio.
The Moon is 365 439 km (227 073 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 364 801 km (226 677 mi).
8 days after descending node on 10 December 2011 at 07:04 in ♊ Gemini. The Moon is located south of the ecliptic over the following 4 days, until the lunar orbit crosses from South to North in ascending node on 23 December 2011 at 11:36 in ♐ Sagittarius.
22 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the second to the final part of the cycle.
7 days since the previous standstill on 10 December 2011 at 13:37 in ♊ Gemini when the Moon has reached North declination of ∠22.554°, the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-22.554° at the point of next southern standstill on 23 December 2011 at 17:25 in ♐ Sagittarius.
In 6 days on 24 December 2011 at 18:06 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.
