Waning Crescent in Gemini

Waning Crescent on . Illuminated surface of the Moon is 25% and getting smaller. Lunar cycle is 24 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 ♊ Gemini

Moon is passing about ∠20° of ♊ Gemini tropical zodiac sector.

2 days after Last Quarter

Previous main lunar phase is the Last Quarter before 2 days on 9 August 2012 at 18:55.

Sturgeon Moon after 19 days

Next Full Moon is the Sturgeon Moon of August 2012 after 19 days on 31 August 2012 at 13:58.

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 ∠1776"

Lunar disc appears visually 6.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1894".

Lunation 155 / 1108

The Moon is 24 days old and navigating from the second to the final part of the current synodic month. This is lunation 155 of Meeus index or 1108 from Brown series.

Synodic month length 29.48 days

The length of this lunation is 29 days, 11 hours and 30 minutes and it is 1 hour and 14 minutes longer than the upcoming lunation's length. 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 shorter than mean

The length of the current synodic month is 1 hour and 14 minutes shorter than the mean synodic month length. It is 4 hours and 55 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠248.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠248.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠283.7°.

Moon after apogee

2 days since point of apogee on 10 August 2012 at 10:51 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 23 August 2012 at 19:39 in ♏ Scorpio.

Distance to Moon 403 526 km

The Moon is 403 526 km (250 739 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 369 731 km (229 740 mi).

Moon after descending node

1 day after descending node on 11 August 2012 at 00:04 in ♊ Gemini the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 24 August 2012 at 11:38 in ♐ Sagittarius.

Moon at northern standstill

At 09:47 the Moon is meeting its standstill point to reach North declination of ∠21.492°. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-21.379° at the point of next southern standstill in ♐ Sagittarius on 25 August 2012 at 18:40.

Draconic month

15 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 5 days

In 5 days on 17 August 2012 at 15:54 in ♌ Leo 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.
