Waning Crescent in Sagittarius

Waning Crescent on . Illuminated surface of the Moon is 13% 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 leaving the last ∠1° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 26 January 2011 at 12:57.

Snow Moon after 18 days

Next Full Moon is the Snow Moon of February 2011 after 18 days on 18 February 2011 at 08:36.

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 ∠1861"

Lunar disc appears visually 4.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1861" and ∠1948".

Lunation 136 / 1089

The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 136 of Meeus index or 1089 from Brown series.

Synodic month length 29.73 days

The length of this lunation is 29 days, 17 hours and 28 minutes and it is 47 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 longer than mean

The length of the current synodic month is 4 hours and 44 minutes longer than the mean synodic month length. It is 2 hours and 19 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠103.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠103.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠139.2°.

Moon before apogee

8 days since point of perigee on 22 January 2011 at 00:10 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 6 February 2011 at 23:13 in ♓ Pisces.

Distance to Moon 385 119 km

The Moon is 385 119 km (239 302 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 405 924 km (252 229 mi).

Moon in ascending node

Moon is in ascending node in ♐ Sagittarius at 18:29 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 14 days until Moon's next descending node later on 14 February 2011 at 08:14 in ♋ Cancer.

Moon after southern standstill

1 day since the last southern standstill on 29 January 2011 at 16:26 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.180° the lunar orbit is extending northward over the next 13 days to face maximum declination of ∠24.080° at the point of next northern standstill on 13 February 2011 at 09:00 in ♊ Gemini.

New draconic month

At 18:29 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 3 days

In 3 days on 3 February 2011 at 02:31 in ♒ Aquarius 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.
