Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 24 December 2009 at 17:36.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♉ Taurus

Moon is passing about ∠9° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1869"

Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1869" and ∠1951".

Cold Moon after 4 days

Next Full Moon is the Cold Moon of December 2009 after 4 days on 31 December 2009 at 19:13.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 123 / 1076

The Moon is 10 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 123 of Meeus index or 1076 from Brown series.

Synodic month length 29.8 days

The length of the 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 the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 6 hours and 25 minutes longer than the mean synodic month length. It is 38 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠135.6°

At the beginning of the lunation cycle the true anomaly is ∠135.6°. At the beginning of next synodic month the true anomaly is going to be ∠164.3°.

Moon before apogee

6 days after point of apogee on 20 December 2009 at 14:54 in ♒ Aquarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next perigee on 1 January 2010 at 20:36 in ♋ Cancer.

Previous apogeeNext perigee

Distance to Moon 383 425 km

The Moon is 383 425 km (238 249 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 358 684 km (222 876 mi).

Moon before descending node

8 days after ascending node on 18 December 2009 at 16:41 in ♑ Capricorn. The Moon is located north of the ecliptic over the following 5 days, until the lunar orbit crosses from North to South in descending node on 1 January 2010 at 12:30 in ♋ Cancer.

Previous nodeNext node

Draconic month

8 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the beginning to the first part of the cycle.

Moon before northern standstill

11 days since the previous standstill on 16 December 2009 at 02:38 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.769°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠25.787° at the point of next northern standstill on 30 December 2009 at 10:09 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 4 days

In 4 days on 31 December 2009 at 19:13 in ♋ Cancer the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
