Moon phase and lunation details

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 18 December 2011 at 00:48.

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.

Moon is entering ♏ Scorpio

Moon is passing first ∠0° of ♏ Scorpio tropical zodiac sector.

Lunar disc appears visually 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1959" and ∠1951".

Wolf Moon after 17 days

Next Full Moon is the Wolf Moon of January 2012 after 17 days on 9 January 2012 at 07:30.

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 147 / 1100

The Moon is 27 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 147 of Meeus index or 1100 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.5 days

Length of current 147 lunation is 29 days, 11 hours and 57 minutes. It is 1 hour and 36 minutes shorter than next lunation 148 length.

Lunation length shorter than mean

Length of current synodic month is 47 minutes shorter than the mean length of synodic month, but it is still 5 hours and 22 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠21.6°

This New Moon true anomaly is ∠21.6°. At beginning of next synodic month true anomaly will be ∠42.1°. 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 in perigee

Moon is reaching point of perigee on this date at 02:56, this is 16 days after last apogee on 6 December 2011 at 01:13 in ♈ Aries. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 11 days ahead, until it will get to the point of next apogee on 2 January 2012 at 20:19 in ♈ Aries.

Previous apogeeNext apogee

Distance to Moon 364 801 km

This perigee Moon is 364 801 km (226 677 mi) away from Earth. It is 2 293 km closer than the mean perigee distance, but it is still 5 555 km farther than the closest perigee of 21st century.

Moon before ascending node

12 days after its descending node on 10 December 2011 at 07:04 in ♊ Gemini, the Moon is following the southern part of its orbit for the next day, until it will cross the ecliptic from South to North in ascending node on 23 December 2011 at 11:36 in ♐ Sagittarius.

Moon before southern standstill

11 days after previous North standstill on 10 December 2011 at 13:37 in ♊ Gemini, when Moon has reached northern declination of ∠22.554°. Next day the lunar orbit moves southward to face South declination of ∠-22.554° in the next southern standstill on 23 December 2011 at 17:25 in ♐ Sagittarius.

Syzygy in 2 days

After 2 days on 24 December 2011 at 18:06 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
