Quarter* ♎ Libra
Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 57% and getting smaller. The 21 days old Moon is in ♎ Libra.
* The exact date and time of this Last Quarter phase is on 5 January 2013 at 03:58 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠6° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 2.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1911" and ∠1951".
Next Full Moon is the Wolf Moon of January 2013 after 22 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 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 160 of Meeus index or 1113 from Brown series.
Length of current 160 lunation is 29 days, 11 hours and 2 minutes. It is 34 minutes shorter than next lunation 161 length.
Length of current synodic month is 1 hour and 42 minutes shorter than the mean length of synodic month, but it is still 4 hours and 27 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠6.8°. At beginning of next synodic month true anomaly will be ∠23.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
9 days after point of apogee on 25 December 2012 at 21:19 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 10 January 2013 at 10:26 in ♑ Capricorn.
Moon is 375 126 km (233 092 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 360 048 km (223 723 mi).
10 days after its descending node on 24 December 2012 at 22:27 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 7 January 2013 at 23:50 in ♏ Scorpio.
23 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
8 days after previous North standstill on 26 December 2012 at 21:24 in ♊ Gemini, when Moon has reached northern declination of ∠20.927°. Next 5 days the lunar orbit moves southward to face South declination of ∠-20.879° in the next southern standstill on 9 January 2013 at 15:22 in ♐ Sagittarius.
After 7 days on 11 January 2013 at 19:44 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
