Moon phase and lunation details
Moonrise and moonset
Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.
Moon in ♊ Gemini
Moon is leaving the last ∠3° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.
Apparent angular diameter ∠1777"
Lunar disc appears visually 9.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1777" and ∠1950".
It is Cold Moon
The Full Moon this days is the Cold of December 2013.
Upcoming main Moon phases
- Last Quarter in Virgo ♍ on 25 December 2013 at 13:48
- New Moon in Capricorn ♑ on 1 January 2014 at 11:14
- First Quarter in Aries ♈ on 8 January 2014 at 03:39
- Full Moon in Cancer ♋ on 16 January 2014 at 04:52
Spring tide
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
Lunation 172 / 1125
The Moon is 15 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 172 of Meeus index or 1125 from Brown series.
Synodic month length 29.45 days
The length of the lunation is 29 days, 10 hours and 52 minutes. This is the year's shortest synodic month of 2013. It is 28 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
Lunation length shorter than mean
The length of the current synodic month is 1 hour and 52 minutes shorter than the mean synodic month length. It is 4 hours and 17 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠336.4°
At the beginning of the lunation cycle the true anomaly is ∠336.4°. At the beginning of next synodic month the true anomaly is going to be ∠353°.
Moon before perigee
13 days after point of perigee on 4 December 2013 at 10:15 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next apogee on 19 December 2013 at 23:49 in ♋ Cancer.
Distance to Moon 403 451 km
The Moon is 403 451 km (250 693 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 406 269 km (252 444 mi).
Moon after descending node
4 days after descending node on 13 December 2013 at 10:10 in ♉ Taurus. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 28 December 2013 at 00:21 in ♏ Scorpio.
Draconic month
16 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.
Moon at northern standstill
At 01:00 the Moon is meeting its standstill point to reach North declination of ∠19.570°. Over the next 13 days the lunar orbit is going to extend southward to face maximum declination of ∠-19.537° at the point of next standstill in ♐ Sagittarius on 31 December 2013 at 04:49.
Sun-Earth-Moon syzygy
The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
