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

Length of current 171 lunation is 29 days, 11 hours and 32 minutes. It is 40 minutes longer than next lunation 172 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 12 minutes shorter than the mean length of synodic month, but it is still 4 hours and 57 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠315°

This lunation true anomaly is ∠315°. At the beginning of next synodic month true anomaly will be ∠336.4°. 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°).

Moon before apogee

15 days after point of perigee on 6 November 2013 at 09:28 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 22 November 2013 at 09:50 in ♋ Cancer.

Previous perigeeNext apogee

Distance to Moon 405 356 km

Moon is 405 356 km (251 877 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 405 446 km (251 932 mi).

Moon after descending node

5 days after its descending node on 16 November 2013 at 05:30 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 30 November 2013 at 16:59 in ♏ Scorpio.

Draconic month

18 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.

Moon after northern standstill

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

Previous standstillNext standstill

Syzygy in 11 days

After 11 days on 3 December 2013 at 00:22 in ♐ Sagittarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
