Moon phase and lunation details

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 21 December 2010 at 08:13.

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 leaving the last ∠2° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.

Apparent angular diameter ∠1965"

Lunar disc appears visually 0.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1965" and ∠1951".

Cold Moon before 4 days

Next Full Moon is the Wolf Moon of January 2011 after 25 days on 19 January 2011 at 21:21.

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 135 / 1088

The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 135 of Meeus index or 1088 from Brown series.

Synodic month length 29.64 days

The length of the lunation is 29 days, 15 hours and 27 minutes. It is 2 hours and 1 minute 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 2 hours and 43 minutes longer than the mean synodic month length. It is 4 hours and 20 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠67°

At the beginning of the lunation cycle the true anomaly is ∠67°. At the beginning of next synodic month the true anomaly is going to be ∠103.5°.

Moon at perigee

Moon is at perigee at 12:24. It is 12 days after previous apogee on 13 December 2010 at 08:34 in ♓ Pisces. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 15 days, until point of next apogee on 10 January 2011 at 05:38 in ♓ Pisces.

Previous apogeeNext apogee

Distance to Moon 368 463 km

This perigee Moon is 368 463 km (228 952 mi) away from Earth. It is 5 955 km closer than the mean perigee distance, but it is still 1 893 km further than the closest perigee of 21st century.

Moon after descending node

3 days after descending node on 21 December 2010 at 14:08 in ♊ Gemini. The Moon is located south of the ecliptic over the following 9 days, until the lunar orbit crosses from South to North in ascending node on 3 January 2011 at 12:48 in ♑ Capricorn.

Draconic month

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

Moon after northern standstill

4 days since the previous standstill on 20 December 2010 at 12:37 in ♊ Gemini when the Moon has reached North declination of ∠24.238°, the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-24.242° at the point of next southern standstill on 2 January 2011 at 10:06 in ♐ Sagittarius.

Syzygy in 9 days

In 9 days on 4 January 2011 at 09:03 in ♑ Capricorn the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
