Last Quarter on . The illuminated surface of the moon is 58% and getting smaller. The lunar cycle is 21 days old.
* The exact date and time of this Last Quarter phase is on 15 January 2004 at 04:46 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 ∠15° of ♎ Libra tropical zodiac sector.
Next Full Moon is the Snow Moon of February 2004 after 22 days on 6 February 2004 at 08:47.
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 1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1932" and ∠1951".
The Moon is 21 days old and navigating through the last part of the current synodic month. This is lunation 49 of Meeus index or 1002 from Brown series.
The length of this lunation is 29 days, 11 hours and 22 minutes and it is 51 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 1 hour and 22 minutes shorter than the mean synodic month length. It is 4 hours and 47 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠15.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠33.9°.
10 days since point of apogee on 3 January 2004 at 20:19 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 19 January 2004 at 19:25 in ♐ Sagittarius.
The Moon is 370 946 km (230 495 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 362 768 km (225 414 mi).
11 days after ascending node on 2 January 2004 at 20:11 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 16 January 2004 at 21:08 in ♏ Scorpio.
7 days since the last northern standstill on 6 January 2004 at 21:36 in ♋ Cancer when the Moon has reached North declination of ∠27.031° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-27.072° at the point of next southern standstill on 20 January 2004 at 06:17 in ♑ Capricorn.
11 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.
In 7 days on 21 January 2004 at 21:05 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.
