Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 28 November 2012 at 14:46.

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 ♌ Leo

Moon is passing about ∠17° of ♌ Leo tropical zodiac sector.

Apparent angular diameter ∠1832"

Lunar disc appears visually 6.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1832" and ∠1947".

Beaver Moon before 5 days

Next Full Moon is the Cold Moon of December 2012 after 23 days on 28 December 2012 at 10:21.

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 159 / 1112

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 159 of Meeus index or 1112 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.44 days

Length of current 159 lunation is 29 days, 10 hours and 34 minutes. It is 28 minutes shorter than next lunation 160 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 10 minutes shorter than the mean length of synodic month, but it is still 3 hours and 59 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠351.3°

This New Moon true anomaly is ∠351.3°. At beginning of next synodic month true anomaly will be ∠6.8°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after apogee

5 days after point of apogee on 28 November 2012 at 19:35 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 12 December 2012 at 23:14 in ♐ Sagittarius.

Previous apogeeNext perigee

Distance to Moon 391 347 km

Moon is 391 347 km (243 172 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 357 074 km (221 875 mi).

Moon after descending node

6 days after its descending node on 27 November 2012 at 17:05 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 11 December 2012 at 15:57 in ♏ Scorpio.

Draconic month

20 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

4 days after previous North standstill on 29 November 2012 at 14:33 in ♊ Gemini, when Moon has reached northern declination of ∠20.924°. Next 8 days the lunar orbit moves southward to face South declination of ∠-20.926° in the next southern standstill on 13 December 2012 at 03:48 in ♐ Sagittarius.

Syzygy in 8 days

After 8 days on 13 December 2012 at 08:42 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
