Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 17 November 2013 at 15:16.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♋ Cancer

Moon is passing about ∠12° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1943".

Beaver Moon before 3 days

Next Full Moon is the Cold Moon of December 2013 after 25 days on 17 December 2013 at 09:28.

Upcoming main Moon phases

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 171 / 1124

The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 171 of Meeus index or 1124 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.48 days

The length of the lunation is 29 days, 11 hours and 32 minutes. It is 40 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 12 minutes shorter than the mean synodic month length. It is 4 hours and 57 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠315°

At the beginning of the lunation cycle the true anomaly is ∠315°. At the beginning of next synodic month the true anomaly is going to be ∠336.4°.

Moon before perigee

15 days after point of perigee on 6 November 2013 at 09:28 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 22 November 2013 at 09:50 in ♋ Cancer.

Previous perigeeNext apogee

Distance to Moon 405 356 km

The Moon is 405 356 km (251 877 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 446 km (251 932 mi).

Moon after descending node

5 days after descending node on 16 November 2013 at 05:30 in ♉ Taurus. The Moon is located south of the ecliptic over the following 9 days, until the lunar orbit crosses from South to North in ascending node on 30 November 2013 at 16:59 in ♏ Scorpio.

Draconic month

18 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 after northern standstill

1 day since the previous standstill on 19 November 2013 at 17:18 in ♊ Gemini when the Moon has reached North declination of ∠19.534°, the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-19.552° at the point of next southern standstill on 3 December 2013 at 16:38 in ♐ Sagittarius.

Syzygy in 11 days

In 11 days on 3 December 2013 at 00:22 in ♐ Sagittarius 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.
