Waning Crescent in Scorpio

Waning Crescent on . Illuminated surface of the Moon is 7% and getting smaller. Lunar cycle is 27 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 is entering ♏ Scorpio

Moon is passing first ∠0° of ♏ Scorpio tropical zodiac sector.

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 18 December 2011 at 00:48.

Wolf Moon after 17 days

Next Full Moon is the Wolf Moon of January 2012 after 17 days on 9 January 2012 at 07:30.

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 ∠1959"

Lunar disc appears visually 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1959" and ∠1951".

Lunation 147 / 1100

The Moon is 27 days old and navigating from the second to the final part of the current synodic month. This is lunation 147 of Meeus index or 1100 from Brown series.

Synodic month length 29.5 days

The length of this lunation is 29 days, 11 hours and 57 minutes and it is 1 hour and 36 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 47 minutes shorter than the mean synodic month length. It is 5 hours and 22 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠21.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠21.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠42.1°.

Moon at perigee

Moon is at perigee at 02:56 about 16 days since last apogee on 6 December 2011 at 01:13 in ♈ Aries the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 11 days until point of next apogee on 2 January 2012 at 20:19 in ♈ Aries.

Distance to Moon 364 801 km

This perigee Moon is 364 801 km (226 677 mi) away from Earth. It is 2 293 km closer than the mean perigee distance, but it is still 5 555 km further than the closest perigee of 21st century.

Moon before ascending node

12 days after descending node on 10 December 2011 at 07:04 in ♊ Gemini the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 23 December 2011 at 11:36 in ♐ Sagittarius.

Moon before southern standstill

11 days since the last northern standstill on 10 December 2011 at 13:37 in ♊ Gemini when the Moon has reached North declination of ∠22.554° the lunar orbit is extending southward over the next day to face maximum declination of ∠-22.554° at the point of next southern standstill on 23 December 2011 at 17:25 in ♐ Sagittarius.

Draconic month

26 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 2 days

In 2 days on 24 December 2011 at 18:06 in ♐ Sagittarius 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.
