Waning Crescent in Sagittarius

Waning Crescent on . Illuminated surface of the Moon is 9% 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 ∠6° of ♐ Sagittarius tropical zodiac sector.

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 28 December 2010 at 04:18.

Wolf Moon after 18 days

Next Full Moon is the Wolf Moon of January 2011 after 18 days on 19 January 2011 at 21:21.

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 ∠1896"

Lunar disc appears visually 2.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1896" and ∠1951".

Lunation 135 / 1088

The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 135 of Meeus index or 1088 from Brown series.

Synodic month length 29.64 days

The length of this lunation is 29 days, 15 hours and 27 minutes and it is 2 hours and 1 minute 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 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 details for

True anomaly ∠67°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠67° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠103.5°.

Moon after perigee

6 days since point of perigee on 25 December 2010 at 12:24 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next apogee on 10 January 2011 at 05:38 in ♓ Pisces.

Distance to Moon 377 997 km

The Moon is 377 997 km (234 876 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 404 976 km (251 640 mi).

Moon before ascending node

10 days after descending node on 21 December 2010 at 14:08 in ♊ Gemini the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 January 2011 at 12:48 in ♑ Capricorn.

Moon before southern standstill

11 days since the last northern 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 day to face maximum declination of ∠-24.242° at the point of next southern standstill on 2 January 2011 at 10:06 in ♐ Sagittarius.

Draconic month

25 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 2 days

In 2 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.
