Quarter ♎ Libra
Waning Gibbous is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 68% and getting smaller. The 20 days old Moon is in ♍ Virgo.
Previous main lunar phase is the Full Moon before 6 days on 28 December 2012 at 10:21.
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon is passing about ∠23° of ♍ Virgo tropical zodiac sector.
Lunar disc appears visually 3.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1888" and ∠1951".
Next Full Moon is the Wolf Moon of January 2013 after 23 days on 27 January 2013 at 04:38.
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 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 160 of Meeus index or 1113 from Brown series.
The length of the lunation is 29 days, 11 hours and 2 minutes. It is 34 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 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 minutes longer compared to 21st century's shortest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠6.8°. At the beginning of next synodic month the true anomaly is going to be ∠23.3°.
8 days after point of apogee on 25 December 2012 at 21:19 in ♊ Gemini. 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 10 January 2013 at 10:26 in ♑ Capricorn.
The Moon is 379 703 km (235 937 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 360 048 km (223 723 mi).
9 days after descending node on 24 December 2012 at 22:27 in ♉ Taurus. 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 7 January 2013 at 23:50 in ♏ Scorpio.
22 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.
7 days since the previous standstill on 26 December 2012 at 21:24 in ♊ Gemini when the Moon has reached North declination of ∠20.927°, the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-20.879° at the point of next southern standstill on 9 January 2013 at 15:22 in ♐ Sagittarius.
In 8 days on 11 January 2013 at 19:44 in ♑ Capricorn 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.
