Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 53% and getting smaller. The 21 days old Moon is in ♍ Virgo.
* The exact date and time of this Last Quarter phase is on 23 December 2005 at 19:36 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Lunar disc appears visually 9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1783" and ∠1951".
Next Full Moon is the Wolf Moon of January 2006 after 21 days on 14 January 2006 at 09:48.
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 73 of Meeus index or 1026 from Brown series.
Length of current 73 lunation is 29 days, 12 hours and 11 minutes. It is 1 hour and 8 minutes longer than next lunation 74 length.
Length of current synodic month is 33 minutes shorter than the mean length of synodic month, but it is still 5 hours and 36 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠306.3°. At the beginning of next synodic month true anomaly will be ∠329.9°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
2 days after point of apogee on 21 December 2005 at 02:49 in ♍ Virgo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 9 days, until it get to the point of next perigee on 1 January 2006 at 22:50 in ♑ Capricorn.
Moon is 402 044 km (249 819 mi) away from Earth on this date. Moon moves closer next 9 days until perigee, when Earth-Moon distance will reach 361 750 km (224 781 mi).
13 days after its ascending node on 10 December 2005 at 04:50 in ♈ Aries, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 24 December 2005 at 10:43 in ♎ Libra.
13 days after beginning of current draconic month in ♈ Aries, the Moon is moving from the beginning to the first part of it.
7 days after previous North standstill on 16 December 2005 at 07:14 in ♋ Cancer, when Moon has reached northern declination of ∠28.378°. Next 7 days the lunar orbit moves southward to face South declination of ∠-28.387° in the next southern standstill on 30 December 2005 at 13:57 in ♐ Sagittarius.
After 7 days on 31 December 2005 at 03:12 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
