Moon phase and lunation details

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 25 December 2013 at 13:48.

Moon in ♎ Libra

Moon is leaving the last ∠1° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

Upcoming main Moon phases

Wolf Moon after 19 days

Next Full Moon is the Wolf Moon of January after 19 days on 16 January 2014 at 04:52.

Apparent angular diameter ∠1883"

Lunar disc appears visually 3.56% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1883" and ∠1951".

Neap tide

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.

Lunation 172 / 1125

Moon is 24 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 172 of Meeus index or 1125 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.45 days

Length of current 172 lunation is 29 days, 10 hours and 52 minutes. It is 28 minutes longer than next lunation 173. This is the shortest synodic month of 2013.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 52 minutes shorter than the mean length of synodic month, but it is still 4 hours and 17 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠336.4°

This lunation true anomaly is ∠336.4°. At the beginning of next synodic month true anomaly is ∠353°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).

Moon before perigee

7 days after point of apogee on 19 December 2013 at 23:49, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 5 days until it gets to the point of perigee on 1 January 2014 at 21:00.

Distance to Moon 380 666 km

Moon is 380 666 km (236 535 mi) away from Earth on this date. At previous apogee point before 7 days, distance is 406 269 km (252 444 mi). Moon moves closer next 5 days until perigee, when Earth-Moon distance reaches 356 922 km (221 781 mi).

Moon before ascending node

14 days after its descending node on 13 December 2013 at 10:10, the Moon follows the southern part of its orbit for the next 1 day untill it crosses the ecliptic from South to North in ascending node on 28 December 2013 at 00:21.

Draconic month

26 days after its beginning, the Moon is moving from the second to the final part of current draconic month.

Previous | Current draconic month | Next

Moon before southern standstill

10 days after previous North standstill on 17 December 2013 at 01:00, when Moon reaches northern declination of ∠19.570°, lunar orbit moves southward for the next 3 days to face South declination of ∠-19.537° in the next southern standstill on 31 December 2013 at 04:49.

Syzygy in 4 days

After 4 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 1 January 2014 at 11:14.
