Waning Crescent in Sagittarius

Waning Crescent on . The illuminated surface of the moon is 29% and getting smaller. The lunar cycle is 24 days old.

Moonrise and moonset

The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon phase and lunation details

Moon is entering ♐ Sagittarius

Moon is passing first ∠3° of ♐ Sagittarius tropical zodiac sector.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 26 January 2011 at 12:57.

Snow Moon after 20 days

Next Full Moon is the Snow Moon of February 2011 after 20 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 ∠1907"

Lunar disc appears visually 2.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1907" and ∠1948".

Lunation 136 / 1089

The Moon is 24 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 after perigee

6 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 9 days until the Moon reaches the point of next apogee on 6 February 2011 at 23:13 in ♓ Pisces.

Distance to Moon 375 777 km

The Moon is 375 777 km (233 497 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 405 924 km (252 229 mi).

Moon before ascending node

10 days after descending node on 18 January 2011 at 00:06 in ♋ Cancer 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 30 January 2011 at 18:29 in ♐ Sagittarius.

Moon before southern standstill

11 days since the last northern standstill on 16 January 2011 at 22:51 in ♊ Gemini when the Moon has reached North declination of ∠24.221° the lunar orbit is extending southward over the next day to face maximum declination of ∠-24.180° at the point of next southern standstill on 29 January 2011 at 16:26 in ♐ Sagittarius.

Draconic month

24 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 5 days

In 5 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.
