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 passing about ∠21° of ♐ Sagittarius tropical zodiac sector.

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 18 January 2009 at 02:46.

Snow Moon after 18 days

Next Full Moon is the Snow Moon of February 2009 after 18 days on 9 February 2009 at 14:49.

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 ∠1769"

Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1949".

Lunation 111 / 1064

The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 111 of Meeus index or 1064 from Brown series.

Synodic month length 29.81 days

The length of this lunation is 29 days, 19 hours and 33 minutes and it is 1 hour and 53 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2009. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 6 hours and 49 minutes longer than the mean synodic month length. It is 14 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠186.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠186.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠213.2°.

Moon before apogee

12 days since point of perigee on 10 January 2009 at 10:52 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 23 January 2009 at 00:11 in ♑ Capricorn.

Distance to Moon 405 100 km

The Moon is 405 100 km (251 717 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 116 km (252 349 mi).

Moon before ascending node

10 days after descending node on 12 January 2009 at 08:34 in ♌ Leo the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 January 2009 at 13:27 in ♒ Aquarius.

Moon at southern standstill

At 14:02 the Moon is meeting its standstill point to reach South declination of ∠-27.081°. This is the year's southernmost lunar standstill of 2009. Over the upcoming 14 days the lunar orbit is going to tilt northward to face maximum declination of ∠27.083° at the point of next northern standstill in ♊ Gemini on 5 February 2009 at 14:55.

Draconic month

23 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 3 days

In 3 days on 26 January 2009 at 07:55 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.
