Moon phase and lunation details

3 days after New Moon

Previous main lunar phase is the New Moon before 3 days on 16 December 2009 at 12:02.

Moonrise and moonset

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

Moon in ♒ Aquarius

Moon is passing about ∠12° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1950".

Cold Moon after 11 days

Next Full Moon is the Cold Moon of December 2009 after 11 days on 31 December 2009 at 19:13.

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 123 / 1076

The Moon is 4 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 123 of Meeus index or 1076 from Brown series.

Synodic month length 29.8 days

Length of current 123 lunation is 29 days, 19 hours and 9 minutes. This is the year's longest synodic month of 2009. It is 31 minutes shorter than next lunation 124 length.

Lunation length longer than mean

Length of current synodic month is 6 hours and 25 minutes longer than the mean length of synodic month, but it is still 38 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠135.6°

This New Moon true anomaly is ∠135.6°. At beginning of next synodic month true anomaly will be ∠164.3°. 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 apogee

Moon is reaching point of apogee on this date at 14:54, this is 16 days after last perigee on 4 December 2009 at 14:12 in ♋ Cancer. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 12 days ahead, until it will get to the point of next perigee on 1 January 2010 at 20:36 in ♋ Cancer.

Distance to Moon 405 731 km

This apogee Moon is 405 731 km (252 110 mi) away from Earth. It is 323 km farther than the mean apogee distance, but it is still 978 km closer than the farthest apogee of 21st century.

Moon after ascending node

1 day after its ascending node on 18 December 2009 at 16:41 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 1 January 2010 at 12:30 in ♋ Cancer.

Moon after southern standstill

4 days after previous South standstill on 16 December 2009 at 02:38 in ♐ Sagittarius, when Moon has reached southern declination of ∠-25.769°. Next 9 days the lunar orbit moves northward to face North declination of ∠25.787° in the next northern standstill on 30 December 2009 at 10:09 in ♊ Gemini.

Syzygy in 11 days

After 11 days on 31 December 2009 at 19:13 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
