Moon phase and lunation

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

4 days after New Moon

Previous main lunar phase is the New Moon before 4 days on 13 December 2012 at 08:42.

Cold Moon after 10 days

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

Moon in Aquarius

Moon is passing about ∠22° of Aquarius tropical zodiac sector.

Upcoming Moon phases

Apparent angular diameter ∠1903"

Lunar disc appears visually 2.42% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1903" and ∠1950".

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 160 / 1113

Moon is 5 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 160 of Meeus index or 1113 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.46 days

Length of current 160 lunation is 29 days, 11 hours and 2 minutes. It is 34 minutes shorter than next lunation 161.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 42 minutes shorter than the mean length of synodic month, but it is still 4 hours and 27 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠6.8°

This lunation true anomaly is ∠6.8°. At the beginning of next synodic month true anomaly is ∠23.3°. The length of upcoming synodic months increases since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after perigee

4 days after point of perigee on 12 December 2012 at 23:14, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 8 days until it gets to the point of apogee on 25 December 2012 at 21:19.

Distance to Moon 376 589 km

Moon is 376 589 km (234 001 mi) away from Earth on this date. At previous perigee point before 4 days, distance is 357 074 km (221 875 mi). Moon moves farther next 8 days until apogee, when Earth-Moon distance reaches 406 101 km (252 339 mi).

Moon after ascending node

5 days after its ascending node on 11 December 2012 at 15:57, the Moon follows the northern part of its orbit for the next 7 days untill it crosses the ecliptic from North to South in descending node on 24 December 2012 at 22:27.

Draconic month

5 days after its beginning, the Moon is moving from the beginning to the first part of current draconic month.

Previous | Current draconic month | Next

Moon after southern standstill

4 days after previous South standstill on 13 December 2012 at 03:48, when Moon reaches southern declination of ∠-20.926°, lunar orbit moves northward for the next 9 days to face North declination of ∠20.927° in the next northern standstill on 26 December 2012 at 21:24.

Syzygy in 10 days

After 10 days the Moon is in Full Moon opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy on 28 December 2012 at 10:21.
