Waning Crescent in Sagittarius

Waning Crescent on . Illuminated surface of the Moon is 8% and getting smaller. Lunar cycle is 26 days old.

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♐ Sagittarius

Moon is passing about ∠17° of ♐ Sagittarius tropical zodiac sector.

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 5 January 2013 at 03:58.

Wolf Moon after 17 days

Next Full Moon is the Wolf Moon of January 2013 after 17 days on 27 January 2013 at 04:38.

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.

Apparent angular diameter ∠1973"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1951".

Lunation 160 / 1113

The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 160 of Meeus index or 1113 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 11 hours and 2 minutes and it is 34 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠6.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠6.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠23.3°.

Moon before perigee

14 days since point of apogee on 25 December 2012 at 21:19 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 10 January 2013 at 10:26 in ♑ Capricorn.

Distance to Moon 363 351 km

The Moon is 363 351 km (225 776 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 360 048 km (223 723 mi).

Moon after ascending node

1 day after ascending node on 7 January 2013 at 23:50 in ♏ Scorpio the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 21 January 2013 at 01:19 in ♉ Taurus.

Moon at southern standstill

At 15:22 the Moon is meeting its standstill point to reach South declination of ∠-20.879°. This is the year's southernmost lunar standstill of 2013. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠20.816° at the point of next northern standstill in ♊ Gemini on 23 January 2013 at 05:12.

Draconic month

1 day since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 2 days

In 2 days on 11 January 2013 at 19:44 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.
